Remove inconsistent index
What does this MR do?
This index was committed to the codebase on a backup table. It resulted in the index on gitlab.com not being consistent with the structure.sql
entry in the codebase.
This table will be removed with #227753 (closed), as it follows a complex data migration regarding deduplication of labels. It's good to have the actual database match our schema though
