Issue
https://otwarchive.atlassian.net/browse/AO3-5667
Purpose
This PR modifies the
filter_taggingstable to replace the existing index on(filter_id, filterable_type)with a unique index on(filter_id, filterable_type, filterable_id).Testing Instructions
The usual steps for testing a migration should be sufficient: run it, then roll it back, then run it again. That should ensure that both the migration and its reverse are working.
