Fix adding new route in front (#9651) 

When adding a new route using "Front", its presentation info
order is set to 1, after the master-bus which has PI order 0.
(see Session::ensure_route_presentation_info_gap).

Mixer_UI::add_stripables, looks up the insert iterator:
"after the route with order 0", but since the master bus is
not in mixer's track-model, the insert-iterator is left "at end".

A later call to `sync_presentation_info_from_treeview` then updated
the new track's order key to be at the end.
