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.

Clarify that this.something is not available in Jest (docs)

Closes #24809

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.

Prevent EE backport migrations from running if CE is not migrated

Closes #63612

Improve Review Apps cleanup when previous deployment failed by only issuing an `helm delete` command

Closes #63639 and #62161

See merge request gitlab-org/gitlab-ce!28661

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>
```

When removing the last file from a folder in WebIDE, do not remove the
folder from the view. We keep those to give users possibility to

Allow autocompleting labels using colons and spaces

Closes #63343 and #56510

See merge request gitlab-org/gitlab-ce!29749

The `:` key will no longer exit out of the autocomplete dialog,
allowing auto-completion of labels with colons in them.

Refactor AfterCommitQueue.inside_transaction?

See merge request gitlab-org/gitlab-ce!29903

This is a small change to move AfterCommitQueue.inside_transaction?
to Gitlab::Database.inside_transaction? Since this change is required
by different changes which may not arrive in sequence, it's easier
to extract this change out on it's own.

When a user sets only_allow_merge_if_pipeline_succeeds, also named
as "Pipeline must succeed" project setting, we require the pipeline
to be present.

This solves race condition issues especially with external CI
providers when a build is triggered externally but no pipelines are
created in GitLab yet.

Document that a head pipeline is expected when using "Pipeline
must succeed" setting. Also explain limitations with the use of
only/except where there may not be any jobs created and the merge
request will not be allowed to be merged.

Fix reports jobs timing out because of cache

Closes gitlab-ee#12021, #60879, and gitlab-ee#11303

See merge request gitlab-org/gitlab-ce!29780

Note: This commit relies on
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26801
which brings support to multiple extends.

While `cache: {}` can disable a cache being set globally, it doesn't
work with extends, which will perform a reverse deep merge based on the
keys.

The cache defined in the base `.default-cache` job
won't be disabled in the report jobs.

As a side effect, the `code_quality`, `sast`, and `dependency_scanning`
jobs are running on a larger code base than expected, leading to
timeouts.
