Marko Mäkelä 609ea2f37b MDEV-17614: After-merge fix ...

MDEV-17614 flags INSERT…ON DUPLICATE KEY UPDATE unsafe for statement-based
replication when there are multiple unique indexes. This correctly fixes
something whose attempted fix in MySQL 5.7
in mysql/mysql-server@c93b0d9a97
caused lock conflicts. That change was reverted in MySQL 5.7.26
in mysql/mysql-server@066b6fdd43
(with a substantial amount of other changes).

In MDEV-17073 we already disabled the unfortunate MySQL change when
statement-based replication was not being used. Now, thanks to MDEV-17614,
we can actually remove the change altogether.

This reverts commit 8a346f31b9 (MDEV-17073)
and mysql/mysql-server@c93b0d9a97 while
keeping the test cases.
