Look up a Tpf.Persona by its TelepathyGLib.Contact.
If the TelepathyGLib.Account for the contact's TelepathyGLib.Connection is
null, or if a Tpf.PersonaStore can't be found for that account, null
will be returned. Otherwise, if a Tpf.Persona already exists for the given contact,
that will be returned; if one doesn't exist a new one will be created and returned. In this case, the
Tpf.Persona will be added to the PersonaStore
associated with the account, and will be removed when contact is destroyed.
