Fix incorrect index name in new 1.28.0 installations

Browse source 
This index name should be the same in new installations as in all other
MySQL installations. This is necessary so that
Special:DeletedContributions does not give an SQL error. Release notes
will go in the 1.28 branch.

Bug: T154872

-- Rename the archive.ar_usertext_timestamp index to usertext_timestamp.
-- This is for MySQL only and is only necessary on wikis freshly installed on
-- 1.28.0 when bug T154872 was present. The patch will probably be removed in
-- 1.29 since we plan on renaming the index properly to ar_usertext_timestamp.
