Email verification banner tests

[nbradbury]

This PR adds basic tests to the email verification banner view model which we recently added to the Me screen, as suggested on the original PR:

The only suggestion for me would be to add an associated view model test suite so that to help any readers understand any or all the use cases involved without needing to have it trigger this whole flow via manual UI testing.

Green CI should be sufficient to test this.

@oguzkocer I hope you don't mind me asking you for a review. I feel like I've worn David out with review requests :) No rush on this as I'm about to take a few days AFK.
