Your Name 471cffcfb0 logind: fix property emission on Sessions 
We would not send the property because we'd call sd_bus_get_current_message()
which would return NULL. If there is no message, we cannot support /self or
/auto, but things are still OK if a path with a session name is given.

Traceback when the issue is triggered:

 #2  we'd call sd_bus_get_current_message() here, which would return NULL, and
     session_object_find() would immediately return 0.
