When the slave processes the master restart format_description event, parallel replication needs to complete any prior events before processing the restart event (which closes temporary tables and such stuff). This happens in wait_for_workers_idle(), however it was not waiting long enough. The wait was using wait_for_prior_commit(), but at that points table can still be open. This lead to assertion in this case. So change wait_for_workers_idle() to wait until all worker threads have reached finish_event_group(), at which point all tables should have been closed.
