Add missing spec for fogbugz importer

See merge request gitlab-org/gitlab!20981

For some reason, `Settingslogic` doesn't always provide the right error
message when the `connection` block is omitted. Sometimes it erroneously
attributes the error section to a different part of the YAML
(e.g. `backup`, `dependency_proxy`).

This commit adds on more information on which `connection` block is
missing from the `gitlab.yml` (e.g. LFS, artifacts, or uploads).

Add security configuration navigation item

See merge request gitlab-org/gitlab!20711

This commit adds a new navigation item to the main navigation. It
sits within a project's "Security & Compliance" submenu and
links to the security configuration screen.

These files were updated automatically with this script:

```
result="$(awk '/[{\[]$/ { printf("%s\t", $0); next } 1' $1)"
echo "$result" > $1
yarn prettier --write $1
```

Includes related import reordering for IDE-related
files to fix eslint warnings.

See issue https://gitlab.com/gitlab-org/gitlab/issues/29243
which tracks the overall effort for migration to Jest.

Running any Rake task would show:

ARNING: Sidekiq testing API enabled, but this is not the test
environment.  Your jobs will not go to Redis.

To fix this, we move the `require` statement into the import task.
Now this message only shows when running the import job.
