Summary - Attempt at fixing the AutocompleteInTeam/empty_string test which is flaky on MySQL-5.6. This is likely an index_merge_intersection optimization issue. See https://community.mattermost.com/core/pl/uzgygwa9e3d4pns14ayfs7mobw for more discussion. The fix here simply modifies the where clause to change the query plan so index_merge_intersection is not used, while also not introducing a temporary table or a filesort.
