Add e_mail_ui_session_check_known_address_sync().
Replaces em_utils_in_addressbook(). Foregos any address caching since any such cache would likely not be updated properly as contacts are added and removed and would lead to incorrect results. An asynchronous variation of this function can be easily added at some future date should a need arise.
