Fix Importing repos from GHE doesn't work

Add link to image URL for images in discussions.

The main problem with this is that it doesn't apply retroactively, only to images that are uploaded after this change. It's also hacky and probably not the most optimal solution.

Resolves #14411.

Remove 2FA status on enable page

The 2FA status on the enabling page is useless, since it always is `disabled`. A user is enabling 2FA, so he already knows that it is disabled.

Fix award emoji picker for relative_url

MR !2888 caused a regression where the emoji picker does not load when
using relative_url, because the path for the controller was hardcoded.

See merge request !3493

This fixes ./spec/services/projects/unlink_fork_service_spec.rb which
somehow started failing on the master branch. It certainly isn't a very
elegant solution but seems to be the easiest/best way of solving this
problem for the time being.

Improve rendering performance of Banzai

Related issues:

* gitlab-org/gitlab-ce#14315
* gitlab-org/gitlab-ce#13651

TODO:

* [x] `Banzai::Filter::ExternalIssueReferenceFilter#call` calls `Project#default_issues_tracker?` which runs a query on every call. Memoizing this only works if the `Project` instance is shared between instances of this filter. Either way it should at most only run this method once.
* [x] Fix the two failing specs
* [x] Clean of the various `call` methods in the filters where I inlined methods
* [x] Remove the `replace_XXX` methods in ReferenceFilter now that they're no longer used.

See merge request !3389

Cleaning this up any further is a bit tricky as the caches in question
should only be evaluated if RequestStore is actually enabled.
