UI: Begin unskipping some more trivial tests (#4574)

WIP Unskip some lower level trivial tests.

This is the beginning of work to unskip some of the more trivial tests that I'd skipped a while back (if the thing they are testing broke, they would have failed higher up in other acceptance tests).

I'd rather keep the tests, as they do test things in a more isolated manner, and the plan was to always come back and work to unskip them time allowing.

I didn't get to far into this work in progress here, but I'd rather merge what I've done all the same and come back at a later date and continue.
