  Bug#28677: SELECT on missing column gives extra error
  
  The method select_insert::send_error does two things, it rolls back a statement
  being executed and outputs an error message. But when a 
  nonexistent column is referenced, an error message has been published already and
  there is no need to publish another.
  Fixed by 1) Factoring out the rollback functionality from select_result::send_error 
  into new public method rollback_statement and making send_error call it. 2) Making 
  handle_select call rollback_statement if an error message was published already.

  Fixed by moving all functionality beyond publishing an error message into 
  select_insert::abort() and calling only that function.
