Hi, following up on the fix for issue #88

A semicolon is added to the end of an operation sql. This breaks existing code that already has a semicolon added at the end. For example:

We have a workflow that looks similar to an example in the docs:
https://cloud.google.com/dataform/docs/reference/sample-scripts#multiple-SQL-operations

DELETE FROM datatable where country = 'GB';
DELETE FROM datatable where country = 'FR';

So now, with the way the extention works, it creates compiled sql like this which is not valid syntax.

DELETE FROM datatable where country = 'GB';
DELETE FROM datatable where country = 'FR';
;
