Emmanuele Bassi 0933ea63c5 Add fallback string for empty inhibit reason 
The public gtk_application_inhibit() API allows a NULL reason argument,
and we have a fallback in place when going through the session manager
proxy; when using the inhibit D-Bus API directly, though, we're just
passing a potentially NULL value to g_variant_new_string(), which will
rightfully complain.
