BUG#18036 - update of table joined to self reports table as crashed

Set exclude_from_table_unique_test value back to FALSE. It is needed for
further check in multi_update::prepare whether to use record cache.

Certain updates of table joined to self results in unexpected
behavior.

The problem was that record cache was mistakenly enabled for
self-joined table updates. Normally record cache must be disabled
for such updates.

Fixed wrong condition in code that determines whether to use
record cache for self-joined table updates.

Only MyISAM tables were affected.

  Fixed failing test case
