It is possible that the kDropTempCollection phase of the compaction coordinator may get restarted even if it has already dropped the ecoc.compact temp collection in a previous run. In this case, it will throw a CollectionUUIDMismatch error, instead of returning the result of the actual compaction operation.

A check needs to be performed before the call to drop for the existence of the collection with the specified UUID. If it exists, then skip the drop operation.
