With worker routing, a Sidekiq queue can have jobs from multiple
workers. This meant `Gitlab::BackgroundMigration.remaining` needed to
account for that possibility. We do that in the same way as we already
did with the scheduled, retry, and dead sets: iterate through and look
for matching records.

We also fix other methods in this class (like `.steal`) while we're
doing this.

This makes sense, because some hooks will fail if the security master
and origin master are very different, but we know (from the generated
command) that the use of push here is safe.
