This commit adds a migration which adds an additional composite index on id, test_id in the tests table. This is needed to help with the performance of queries that are being generated by the openstack-health dashboard's rest api. As part of this migration though some additional cruft in the test_run indexes is cleaned up. We accidently were ending up with duplicate indexes on the id columns in the test_runs table. This removes the duplicate and fixes the check to ensure new DBs don't end up with duplicate indexes. Change-Id: I9d4d42aaa6232db0b2ddfaf8d1a5f079cbeb6b31
