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.

Errors in application settings panel shows wrong panel

See merge request gitlab-org/gitlab-ce!25434

To make this happen, we need to conditionally add the group_saml
strategy when running tests, but only on EE. This requires some changes
to Gitlab.ee? so that it can be used before/without loading the Rails
environment. We also have to change how we require a few files, so this
can run outside of Rails.

Updating multiple application settings panels through
a single action causes the incorrect action to be shown
when there are errors.  Instead, make each panel action
handle both updating and display.
