modem-manager: workaround issue in 'GDBusObjectManagerClient'

Browse source 
The 'GDBusObjectManagerClient' won't signal added or removed objects when it
was created but no name owner was available in the bus. We can still use it for
name-owner changes, but in order to have added/removed object signals, we'll
need to re-create the whole 'MMManager' when we know the service came alive in
the bus.

See GLib/GIO/GDBus bug:
