fix(fast-element1): fix toolbar navigation tests

[m-akinc]

Pull Request

📖 Description

Ten of the fast-foundation toolbar tests (related to focus) began failing seemingly due to browser changes. The tests fail in Chrome as well as Firefox. It seems that calling focus() on the toolbar element does not pass the focus on to a contained element. I've worked around this for nine of the tests by directly focusing a button initially, instead of focusing the toolbar and expecting the button to get focus. The tenth failing test is testing exactly the behavior that stopped working. I believe we will have to just disable that test.

Also, removing a stray .only that was apparently checked in accidentally.

I would imagine these changes are pretty non-controversial, especially since they fix tests that currently do not pass in this branch. @janechu are you comfortable merging this without @chrisdholt's review?
