* Update the keys we consider to unverify a card

Previously when almost anything changed we would unverify a card. But
this was way too aggresive. We really only want to unverify when a query
changes. Far simpler to specify the keys we do want to consider rather
than the keys to ignore.

Was prompted because when we marked a question as a dataset it would
unverify because the `:display` was changed and also `:dataset`. Neither
of these matter for verification purposes

* Update testing context string [ci skip]

* Empty commit to trigger CI

had skipped ci since it was a docstring change but that prevents merging
sad face :(
