Discard existing interfaces

Avoid the need for syncronization between the mapper and services
emitting interfaces added signals by discarding interfaces that have
already been discovered.  This can happen when ia service emits the
interfaces added signal in quick sucession to the name owner changed
signal, and the mapper discovers the new interface while handling
the name owner changed signal.
