fix(typescript): use correct ts version and fix promise types

Angular's compiler CLI requires typescript@^1.9.0-dev. The built-in
Promise typings for that version of	TS don't play well with Firebase
Promise when using Promise.resolve, so the firebase_sdk_auth_backend
has a function that will cast the promises as the correct type.
