test: Enable and cleanup GetTagsTest.

These tests actually tests both the get_tags() function, and the
handle_tags() function. The latter don't work, and should probably be
split into it's own test cases.

There's also some stubs here that we may want to deal with in another
way.

Also removed meaningless "test" of intval() builtin function. It behaves
as documented, no need for us to test it.
