MDEV-18865 Assertion `t->first->versioned_by_id()' failed in innodb_prepare_commit_versioned

Browse Source 
Cause:
* row_start != 0 treated as it exists. Probably, possible row permutations had not been taken in mind.

Solution:
* Checking both row_start and row_end is correct, so versioned() function is used
