Fix editor-mixer update when deleting a Route before a VCA

When deleting the last track before a VCA, on-delete the editor-mixer
switches to display the next TAV.  If that turns out to be a VCATAV,
the editor-mixer will ignore it and keep displaying the deleted route,
holding a shared pointer reference (ports won't be dropped, etc etc).
