Streamline some tests

Move logic testing of validators from the UI tests to unit.
Don't test Hibernate email logic.
Add a small check on goToHome to make sure we actually got home.
Remove RetryRule - was causing more problems than it fixed, such as altering failure reasons and hiding real failures.
Add webhooks to test plan, move project tests to separate class.
Shift login actions to a single step where possible.
Is that not what I did? :confused:
