Clean up users left behind by check_mentions_for_xss_spec on staging
The test check_mentions_for_xss_spec
creates users but doesn't remove them afterwards.
There are now 337 pages of users on Staging created by that test.
We need to delete those users.
I've also submitted an MR to update the test so at least the list won't keep growing: gitlab-org/gitlab!48567 (merged)
