Subject: [PATCH] Bug1930: should draw bottom channel when append-recording...

... Bug happened only when append-recording by pressing the toolbar button, not
by using a shortcut key; and the blank track did get drawn if you moused over
it or hid and showed the window.

Turns out TrackPanel::ProcessUIHandleResult did the needed update, which was
lacking otherwise.  Now TrackList::UpdatePendingTracks is called in another
place.
