MDEV-31523 Using two temporary tables in OPTIMIZE TABLE lead to crash

Browse Source 
Fixed typo in mysql_admin_table which cused call of
close_unused_temporary_table_instances alwas for the first table
instead of the current table.

Added ASSERT that close_unused_temporary_table_instances should not
remove all instances of user created temporary table.
