Lost Debug_sync signal in rpl_sql_thd_start_errno_cleared

Details

    Description

      The test rpl.rpl_sql_thd_start_errno_cleared can lose a debug_sync signal, as there is a RESET immediately following a SIGNAL:

      set debug_sync= "now signal sql_thread_continue";
      		 
       
      		 
      set @@global.debug_dbug= @saved_dbug;
      		 
      set debug_sync= "RESET";

      When the signal is lost, the sql_thread is stuck in a WAIT_FOR clause until it times out, resulting in long test times (albeit still successful).
