Fix randomly failing specs (possibly caused by DatabaseCleaner)

## What does this MR do?

This MR ensures that DatabaseCleaner.clean runs AFTER Capybara's cleanup. This is needed because it *seems* like database is being truncated before capybara session ends, which leads to `undefined method ... for nil:NilClass` exceptions causing tests to randomly fail.

## Are there points in the code the reviewer needs to double check?

Failing spec is https://gitlab.com/gitlab-org/gitlab-ce/blob/master/spec/features/boards/boards_spec.rb. Here are some examples of failed builds: 

- https://gitlab.com/gitlab-org/gitlab-ce/builds/3352437
- https://gitlab.com/certik/gitlab-ce/builds/3359940
- https://gitlab.com/gitlab-org/gitlab-ee/builds/3365914

## Why was this MR needed?

I've noticed that many branches suffer from random failures and it's not very comfortable for big test suite. Re-running builds until they pass is not a solution so I tried to come up with a fix. Unfortunately I can't be 100% sure about this fix (flaky test is always green on my local environment, so I can't be sure if green build on CI is false-positive or not), but if database is really being cleaned too early (which is clearly proved by logs provided here https://gitlab.com/gitlab-org/gitlab-ce/issues/21841#note_14926675 then it's very likely that this fix will help to get rid of random failures.

Also it's officially recommended in DatabaseCleaner README to use `append_after` hook instead of just `after` because of the way RSpec runs after hooks (in reverse order):

> It's also recommended to use append_after to ensure DatabaseCleaner.clean runs after the after-test cleanup capybara/rspec installs.

Fix layout issues with blame table

Refactor sidebar logic for more predictable behavior

## What does this MR do?

Fixes a few bugs with the sidebar and "pin" functionality:

1. Pinned state would get reset when loading a page with a viewport smaller than 1024px (#19183)
2. Toggle buttons could occasionally end up in an invalid state in which the toggle is hidden from view at the same time the sidebar is collapsed.
    ![2016-09-03-09.39.07](/uploads/75d9a836ab58aae9f89f38cc29e90bbd/2016-09-03-09.39.07.gif)

3. Clicking outside the sidebar to trigger 'collapse' when below the 1024px breakpoint would work only if not pinned, even though pin status should only effect the sidebar above the 1024px breakpoint.
4. Code confusing with no single source of truth for the state of the sidebar.  Sometimes pinned state is inferred from the cookie, sometimes from the DOM.  Code to handle these functions was confusingly split across both `sidebar.js` and `application.js` for no apparent reason.

I've created a singleton ES6 class to handle the sidebar DOM manipulations, using the properties `isExpanded` and `isPinned` as the canonical state and providing a `renderState` method to sync the DOM with this state whenever it needs updating.  This avoids the possibility of invalid states caused by reliance on jQuery `toggleClass()` methods and makes the code much more readable/maintainable.

## Are there points in the code the reviewer needs to double check?

It is a substantial rewrite, so I could use another set of eyes to make sure nothing was left behind from the original implementation.

## Why was this MR needed?

I initially intended to just fix #19183 by modifying the code in place, but it proved to be a difficult mess and rather than add to the technical debt it made sense to write a more readable implementation of the sidebar functionality.

sync sidebar DOM state on page:change to minimize split-second appearance of the sidebar in certain situations

Old deployments of Gitlab might have a big number of old events to be
deleted. Such numbers cause the worker to timeout.
I've limited the amount of rows that should be destroyed at once to
10000, and increased how often pruning shall take place to 4 times a
day.

Since contribution calendar shows only 12 months of activity,
events older than that time are not visible anywhere and can be
safely pruned saving big amount of database storage.

Fixes #21164

Add issues filters reset btn

## What does this MR do?

Adds a button to the issues filter to reset all filters. I also lightly refactored a nearby method.

## Are there points in the code the reviewer needs to double check?

At the moment, the user can click the reset button even when no filters have been set. I didn't really like how it looked flashing the link on and off depending on whether a user had added a filter. I prefer having it there all the time, so the user is aware of it. But it wouldn't be difficult to hide if no filters have been set, if that's preferred.

## Why was this MR needed?

So users can reset filters when they're filtering issues.

There is a sample in this document showing the possible values of the predefined CI variables. Those of **CI_SERVER_REVISION** and **CI_SERVER_VERSION** were mixed up. I fixed that.
