Optimize discussion notes resolving and unresolving

## What does this MR do?

Optimize discussion notes resolving and unresolving

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

Some changes had to be made to the discussion spec to account for the fact that notes are not  individually updated now. I only focused on adapting them for the purpose of the regression fix, but admittedly they could be further improved in readability.

There were a number of issues:
    
1. Sidekiq async tasks were being run after project namespaces were deleted. Use Sidekiq in fake mode to prevent this from Sidekiq tasks from being enqueued in the first place.
2. Some outstanding Ajax requests (e.g. autocomplete) were still being loaded while `DatabaseCleaner` ran
3. `logout` did not always wait for logout actually to complete

Fix unnecessary horizontal scroll area in pipeline visualizations

## What does this MR do?

Removes a min-width attribute for the build pipeline visualization wrapper

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

I am curious why this line was there in the first place.  Perhaps I'm just not seeing it.

## Why was this MR needed?

I was noticing an unnecessary horizontal scroll bar when viewing pipeline visualizations embedded in merge request builds tab:

## Does this MR meet the acceptance criteria?

As this is a very simple cosmetic change, I don't think it warrants inclusion in the changelog, documentation, or tests.

Fix an error where we were unable to create a CommitStatus for running state

Due to severe refactoring of Pipeline we introduced regression in how CommitStatus is handled. We received an report that it's impossible to create a CommitStatus with state `running` when there were not previous status. 

The support for Commit Statuses should be simplified. Right now I'm doing minimal change to move forward and fix a bug, but I'll create a new MR that will move all logic that is now part of `lib/api/commit_statuses.rb` to separate service to simplify the implementation.

This error happens due to the fact that we introduced additional status of builds: `created`.

Reduce intermittent spec failures by making VueJS resource interceptor decrement outstanding resource counts when HTTP response is received

Before the count would be reduced 500 ms after a DOM update tick, which could cause race conditions since the `DatabaseCleaner` could run in the middle of a Rails controller handling the response.

Partial fix to #21197 and other intermittent spec failures.

Fix expiration date picker after update

lib/backup: fix broken permissions when creating repo dir

## What does this MR do?

This MR fixes an issue where gitlab:backup:restore will not work because the repositories directory is set up with bad permissions. The bad permissions will prevent access to the repositories by the git user, causing all kinds of troubles (e.g. gitlab-shell won't install hooks).

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

## Why was this MR needed?

Rake task gitlab:backup:restore would complete successfully, but gitlab:check will report errors and gitlab cannot access repos.

## Screenshots (if relevant)

* repositories.old.1472478726 was created without the fix
