/**
		 * The migration "Version0161Date20190902103701" created a unique index for account_id and name without
		 * specifying a name. Unfortunately, this resulted in different index names depending on the table
		 * prefix, which means we now have to loop through the indexes to find the correct one.
		 *
		 * This migration is from 2023-11 and, by now, most people should already have it. Although it is not
		 * recommended to change migrations after they have been released, we are still updating this
		 * one for correctness as it was supposed to drop the index here.
		 *
		 * On newer versions, this will be a no-op, as creating the index
		 * in "Version0161Date20190902103701" is commented out.
		 *
		 * @see \OCA\Mail\Migration\Version0161Date20190902103701::changeSchema
