By default the multiline option for the db api was included in
PyMySql<0.8 but now that it is removed[1] we need to pass in the
multi=True argument to the cursor to maintain the same execution
behavior. Unfortunately, I wasn't sure on how to do that
so I modified the op.execute method to run the sql commands one
line at a time instead. It seems to work for the test cases.
