Fix import error handling

Fixes https://gitlab.com/gitlab-com/support-forum/issues/745

This improves import error handling:
- Now if there's an error during importing before the job is scheduled, we also mark the project status as failed.
- Refactored setting the status to failed into one single method.
- Fixed some situations where the error message was missing or simply empty.

Fix serious performance bug with rendering Markdown with InlineDiffFilter

Nokogiri's `node.replace` was being unnecessarily called for every text node in
the document due to a comparison bug. The code previously was comparing the
HTML representation of the full document against the text node, which would
always fail. Fix the comparison to just compare the modified text.

Closes #18011

Fix link to blank group icon

When the group is the default blank icon, this needs to use the
`image_path` helper; otherwise, the link won't work if assets are
precompiled. This still works fine for uploaded icons in either case.

Closes #14446.
