Add parsing tests for saved queries

This probably should have been part of #148, but we forgot. I'm adding
these tests here because I plan to add `label` to the `SavedQuery`
protocol in the coming commits. With that, I'll want to updated the
parsing tests to check it. To do that, the tests need to exist.
