change idle priority of Editor::redisplay_track_views() 

It appears that GDK/glib will not run idle callbacks with a lower priority than
HIGH_IDLE+10 *if* a new user input event is pending. This means that if mouse
motion events are arriving and causing resizes of selected tracks, the call
to ::redisplay_track_views() which is needed to update all the other tracks,
will not take place if a new motion event arrives. Changing the priority to
same as is used for the ::idle_resize() callback prevents new motion events
from being handled before ::redisplay_track_views() is called.
