Disable retries for remote mirror update worker

By default, Sidekiq will retry 25 times with an exponential backoff.
This may result in jobs retrying for up to 21 days. That could lead
to an ever-increasing queue size for the remote mirror updates. The
mirrors will attempt to update again within an interval, which should
be sufficient.

Added a weight filter reset scenario

Looks like we missed a scenario for testing weight filtering for EE.

I'm not 100% this is the correct implementation, maybe I have to `create(:weight)` but I did this in the web UI so will adjust the spec if they fail.

Added Element extension with .matches and .closest

## What does this MR do?

This adds `.matches` and `.closest` polyfills that will help when removing/not using jQuery. I added these in another MR which was then refactored to not require these methods, but I thought we might as well not lose the code.

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

## Why was this MR needed?

Help when removing/not using jQuery.

Added various stylistic changes to commit title area

## What does this MR do?

After https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6994 was merged, there were some things left over.

## Are there points in the code the reviewer needs to double check?
Yes, in general the code.

Apart from that I couldn't get the extended commit sha to lign up correctly on smaller screens

## Why was this MR needed?
Some things weren't done yet.

- Commit description and commit sha are now bold like in the original design, and are also both visible on smaller screens
- You can now extend the commit sha on bigger screens and keep it visible truncated on smaller screens.
- options dropdown button now correctly displays on smaller screens (similar to issue/mr view)
