MDEV-17913 Encrypted transactional Aria tables remain corrupt after c…

…rash recovery, automatic repairment does not work

This was because of a wrong test in encryption code that wrote random
numbers over the LSN for pages for transactional Aria tables during repair.
The effect was that after an ALTER TABLE ENABLE KEYS of a encrypted
recovery of the tables would not work.

The test cases will be pushed into 10.5 as it requires of several changes
to check table that safer not to backport.
