Check CALL_PHONE and MANAGE_OWN_CALLS permission in placeCall

Staticaly check CALL_PHONE and MANAGE_OWN_CALLS depending on the
PhoneAccountHandle package name passed in instead of taking into
account whether or not the PhoneAccountHandle is associated with
a registered self-managed ConnectionService. This makes sure
we do not leak Telecom state with respect to which PhoneAccounts
are registered back to the caller.
