MDEV-27992 DELETE fails to delete record after blocking is released
MDEV-27025 allows to insert records before the record on which DELETE is
locked, as a result the DELETE misses those records, what causes serious ACID
violation.
Revert MDEV-27025, MDEV-27550. The test which shows the scenario of ACID
violation is added.
