* specialpages-group-oath
This was for grouping the OATHAuth special pages in their own section, but
we have them in the general users and rights (specialpages-group-users) one
instead.
* oathauth-token
Removed as part of the post-AuthManager clean-up (e38c68c).
* oathauth-invalid-key-type
Used to be thrown from maintenance/UpdateForMultipleDevicesSupport.php
until that support was moved into the database (6ef3d24).
