Test automation identity

Hopefully final test for identity to change password. Also a small potential fix for flakiness of facebook signin and some refactorings.
From an object oriented point of view it makes no sense to lump two things together but if you feel so strongly about it, I will make a NewPasswordAndStartPage case class. But imo that is a stupid class to make. It has zero re-usability and does not fit in any object domain.
