set updated_at manually to avoid ORM overwriting my changes

Browse Source 
when ORM level changes are made (eg `my_model.my_column = my_value`),
the ORM will read the column definition to see if it should apply any
defaults.The updated_at columns that we use all define
`onupdate=datetime.datetime.utcnow`. We can't patch this out as the
function pointer to the original function has already been grabbed by
this at import time - so freezegun or `mocker.patch` won't work.

So we have to use the query syntax to set the `updated_at` timestamp in
the DB without going through the ORM layer.
