Squelch output of ActiveSupport::Cache::NullStore in tests

See merge request gitlab-org/gitlab-ce!30055

When a spec fails relating to the cache, the job log can easily exceed
the maximum length and make it harder to see the actual issue
(e.g. https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/239803017).

Move vuex action helper spec to Jest

See merge request gitlab-org/gitlab-ce!29653

This is largely a straight-forward copy of the Karma spec, with the
usual Karma->Jest necessary changes.

This also fixes a bug in the implementation that was causing the tests
to fail, when run on Jest/node, whereby actions that return rejected
promises would always fail the given test. This was due to those
rejections not being caught in the same call stack in which they were
created.

Upgrade Gitaly to v1.49.0

Closes gitaly#1738

See merge request gitlab-org/gitlab-ce!29990

The setup was wrong, and due to Gitaly being a bit more strict it had to
match up. The test is now accurate and passing again.

If CRON=1 is in use, we shouldn't generate any output or admins may be
notified via e-mail about unnecessary warnings.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/63703

If a user upgraded to any GitLab 11.x EE version but switched
back to CE, it's possible the state of the EE tables are not
in the right state for the EE backport migration to work properly.
In particular, there were three tables that had trouble:

* epics
* geo_event_log
* vulnerability_feedback

The EE backport migration would fail while trying to add foreign key
constraints because a key didn't exist in the table. This happens
because any EE migration that add or removed columns between v11.0.0 and
v11.11.3 are not guaranteed to be applied in an CE installation. The EE
backport schema does not individually backport these migrations.

We now check if certain columns are present to determine whether
the backport migration is in the proper state. CE users are required
to upgrade to v11.11.3 EE if they ever installed EE previously before
they can go back to v12.x CE.

Tested via:

```
git checkout -f v11.0.0-ee
bundle exec rake db:reset
git checkout .; git checkout -f v11.11.3
bundle exec rake db:migrate
git checkout .; git checkout -f v12.0.0
bundle exec rake db:migrate
<failure happens>
```
