PROV-1071 Removed 2 remaining MyISAM tables

In the process I had to fix the MediaContentLocationIndexer. It seems
to work okay now. There was an unused ‘page’ column in the table that
didn’t have a default set. It’s gone now.
PROV-1071 InnoDB fulltext indexes are MySQL 5.6+ so we can't use them quite yet

Now use normal index instead. Should be okay since all we do is some
LIKE queries on a column that usually has 1 word per row, 2 tops.
