[telepathy-gabble/master] tube-dbus: check if the tube has been requested to determine if we need to offer it

[Guillaume Desmottes]

If we rejoin a muc containing old D-Bus tubes we previously created they
now have the "Local Pending" state as expected instead of "Not Offered".
This fix b.fd.o #23678 as such tubes are now listed in
Tubes.ListTubes().
