Add tests for tag information rendering

These should have been added when we started rendering this information in
e5b09f3; apparently I was too lazy back then. Adding them now to guard
against breaking it in the next commit.

I'm adding these to the CRUD tests, it doesn't seem worth adding separate tests
just for these assertions.
