mm-iface-mode: provide direction and number when creating calls

Calls created from property bundles are always outgoing, while calls
created as input events from URCs during runtime are always incoming.

This change makes it mandatory to provide at least direction of the
call when the object is created, leaving the number as an optional
property that may or may not be known in advance (e.g. it would be
optional only for incoming calls).
