Reduce intermittent spec failures by making VueJS resource interceptor decrement outstanding resource counts when HTTP response is received

Before the count would be reduced 500 ms after a DOM update tick, which could cause race conditions since the `DatabaseCleaner` could run in the middle of a Rails controller handling the response.

Partial fix to #21197 and other intermittent spec failures.

See merge request !6224

Change "check out, review, and merge locally" URL to SSH by default.

## What does this MR do?

Change the default URL type  in the "Check out, review, and merge locally" pop-up dialog to SSH.

## Why was this MR needed?

The default URL to show on the project screen is the SSH URL, so it makes sense for it to be the default here too. Plus, since most people (hopefully) use SSH keys to avoid typing credentials repeatedly, changing this default means these commands can be pasted into a terminal more easily since no password prompt will get in the way.

Clean up search result classes

This commit adds a job to the pipeline to test if migration on seed
data works. Even though the seed data is not perfect, it does give more
guarentees that this will succeed in the real world too.

seed_fu is used instead of dev:setup to save some time, as they both
generate the data in the same way, this should be fine.

First check if there is a result on the migration, else there is
nothing to do
