Fix sporadic test failure in rpl.rpl_create_drop_event

Browse source 
Depending on timing, an extra event run could start just when the event
scheduler is shut down and delay running until after the table has been
dropped; this would cause the test to fail with a "table does not exist"
error in the log.
