Loads move issue dropdown async

To keep the style of the dropdown the same as the other dropdowns in the issue form, it uses select2 rather than our new dropdowns.

Fixed JS error when trying to remove discussion form

## What does this MR do?

Fixes a JS error which was caused by an ID of the form not matching what was returned by the JSON. Instead of checking that, it gets the current form from the ajax success event.

This would only happen on outdated discussions because the ID of the discussion form ends with `-false` because it isn't active. However, the note is added to an active discussion so the ID returned actually ends in `-true` & therefore the JS couldn't find the correct form.

## What are the relevant issue numbers?

Closes #17778

Replace `link_to_gfm` with `link_to` in merge request and issue titles.

## What does this MR do?
This removed GitLab Markdown Formatting from issue titles due to issues and confusion it caused as well as performance reasons.

On the issue/MR page itself, the formatting is preserved. This only effects index pages. See:

![Screen_Shot_2016-05-24_at_3.31.17_PM](/uploads/8857ed7f3cc6a47ea41ca88134e5d17a/Screen_Shot_2016-05-24_at_3.31.17_PM.png)

I think the trade-off here is worth it, otherwise we'd just be playing wack-a-mole.

## Are there points in the code the reviewer needs to double check?
I don't think so.

## Why was this MR needed?
Previously if an issue had an emoji for its name it would be unclickable. Similarly, links were rendered inline if the title was something like “Fixes a bug with https://google.com”. This confused a number of users, so it’s removed.

This is also ever so slightly more performant :)

## What are the relevant issue numbers?
This fixes #17614 and #17230.

POC: Updated contrib calendar

In an effort to cut down the JS file size - i've removed the heatmap calendar used for the contributing calendar on users profiles. We already have d3 on the page so why not use it instead of using a library which uses it?
