workaround for forks with an invalid repo

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/13465

The error occurs when a project returns a `nil` commit for a variety of reasons, I assume the repository is corrupt - perhaps as a result of a failed fork. 

With this MR, we do not show forks with corrupted repos in the list of forks, as this does not seem to work anyway. A better solution is to fix the cause of the issue and/or any data integrity problem...

Also fixing Sentry issue: 1180
`undefined method 'already_forked?' for nil:NilClass `

Uses cross browser niceScroll to do scrolling on sidebar.

Fixes: #13544 

Firefox does not support `-webkit-scrollbar` and there is no alternative for FF. So for example Gmail falls back to no fancy scrollbar. Stuck with jQuery, which is a good solution, since we already use it. 

This also leaves the default scrollbar as is.

Reduce code complexity on GitPushService#execute

Code complexity for gitlab-ce after this has been refactored:
```
  27.3: GitPushService#execute
```
This still needs to be merged into `gitlab-ee` presumably with conflicts... Perhaps we should create another issue for doing that?

I left the code sort of similar to what it was... If I could, I would have refactored most of the code into separate classes, etc. as it breaks probably all SOLID principles.

Re-add section about NGINX config and init script updates in 8.4->8.5 update doc

These sections were removed by !2766 but:
- even if the NGINX config wasn't modified, it might
  be in future updates so it's better to always have
  it instead of having to remember to add it depending
  on the changes
- the init script update section must be there since
  it's a safe command line that should be run on every update

This fixes https://github.com/gitlabhq/gitlabhq/issues/10031.
