adds more tests for api.Symbols

I overlooked some of the tests that should be added to the public API.
This commit fixes my mistake. Also see 027b00171c.

To reiterate the reasoning behind introduction of test methods into the API.
I'd argue that the API duplication w.r.t flags is trumped by unified interface
to tests and better encapsulation (especially since some of the flags have
different meaning depending on whether the flaggee is a term or a type).
