Bug#38499: flush tables and multitable table update with
derived table cause crash
When a multi-UPDATE command fails to lock some table, and
subsequently succeeds, the tables need to be reopened if
they were altered. But the reopening procedure failed for
derived tables.
Extra cleanup has been added.

Added test case for bug #38499.
