Making the `gettext:updated_check` by completely regenerating the gitlab.pot.

This avoids an issue where `gettext:find` would not pick up on changes
if the file isn't removed first.

Move mailer preview to app directory

See merge request gitlab-org/gitlab-ee!6405

We saw in production that DispatchWorker was running about twice an hour,
which would schedule twice as many jobs as it should.

For some reason, BatchWorker was running 1000 times per hour, possibly
due to Sidekiq RSS kills that caused these jobs to restart.

Adding an ExclusiveLease prevents these jobs from running more
than they should.
