Now that Resources don't share attributes, Fork doesn't have Project
attributes. That caused the merge fork test to fail because it no
longer had access to repository_http_location via Fork. Rather than
give Fork Project attributes directly, we add a project attribute to
Fork and populate it via the API at the end of the fabricate! method
after the fork has been created via the UI.

We also update the merge fork test to be slightly more concise and
consistent with newer tests by using perform with proc coercion
instead of act or perform with the full block syntax.

but different attribute values

Retries in Sidekiq and in the remote mirror scheduler can cause repeated
attempts in quick succession if the sync fails. Each failure will then
send an e-mail to all project maintainers, which can spam users
unnecessarily.

Modify the logic to send one notification the first time the mirror
fails by setting `error_notification_sent` to `true` and reset the
flag after a successful sync.

`spec/features/uploads/user_uploads_file_to_note_spec.rb` was failing in
master because MySQL detected a deadlock when a DELETE and INSERT for
the same indexed item occurred within a transaction in the `uploads`
table.  Due to InnoDB's next-key locking algorithm
(innodb_locks_unsafe_for_binlog in
https://dev.mysql.com/doc/refman/5.5/en/innodb-parameters.html), InnoDB
sets an exclusive lock for any of the indexed records it encounters, so
the INSERT will fail until the DELETE is committed.

To fix this, we just disable the transaction for MySQL and keep
it for PostgreSQL.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/55161
