When migrating some code from dbus-python, I ran into this exception:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: None.GetValue with signature "" could not be found

It turns out that the other end is calling a method without specifying the interface. While this can be worked around by fixing the other end and always specifying an interface, it should be trivial to adapt the _matches method of a message, probably here, to ignore the interface if it is None.

make interface optional on method calls

The dbus spec allows the interface to be optional on
method calls. In that case, allow the message to match
on any method with a matching name and signature.

I went about fixing it slightly differently, more explicitly calling _matches from the message_bus module without an interface when it is None.
