[pgadmin-hackers] pgAdmin 4 commit: Properly detect when files have changed in thequery

Properly detect when files have changed in the query tool and set the dirty flag accordingly. Fixes #1807

Note that (like pgAdmin 3) we don't make any attempt to detect if all changes have been undone and completely reverted
asthat could be very expensive with large scripts.
