migration: Drop redundant query-migrate result @Blocked

Result @Blocked is redundant. Unfortunately, we realized this too close to the release to risk dropping it, so we deprecated it instead, in commit e11ce6c. Since it was deprecated from the start, we can delete it without the customary grace period. Do so.
