Refresh branch cache after `git gc`

As discussed in !5160, we should refresh the branch name list after expiring to make sure we are in a good state and that we do not affect view performance (as much).

Fix import_data being saved as a result of an invalid import_url

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/19479

Seem that in all cases the `import_url` was an empty string. The `import_url` is now validated correctly and no longer creates the `import_data`even if it fails validation. <= Should cover cases 1, 3, and 4 of https://gitlab.com/gitlab-org/gitlab-ce/issues/19479#note_13005276

Also, it now rescues from all exceptions when importing from a URL, so we make sure the `import_status` is failed after that. Covers case 2 of https://gitlab.com/gitlab-org/gitlab-ce/issues/19479#note_13005276

Cleanup feature proposal template

## What does this MR do?

Changes the recommended template for feature proposals.

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

## Why was this MR needed?

I've been using the template for a while, and find that putting so many words into the h2 makes me think there's actual content there, until I realize I'm just reading the template text (again). I think we can get away with just putting `Description` as the header, and putting the suggested content for that section as plain text below for someone to replace.
