This MR adds a new option in the filtered search: Epic. With this
change, when the hint dropdown opens, epic will be an option. Upon
selecting, all the epics in the parent group will be displayed. When an
epic is selected, the only issues contained in the epic are displayed.
This also supports the new NOT operator.

Rename file too

When upgrading to 12.8 EE, the initializer might fail with
`NoMethodError: undefined method `pluralize' for LicenseHelper:Module`
if the license neared expiry. This happened
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/24998 changed the
database check so that the license warning would actually be displayed,
but inside an initializer `pluralize` is not available.

The easiest way to fix this now is to revert the database check to the
original version.
