file chooser: Avoid doing excess work

Browse Source 
Whenever we change directories, we unset the model, and then
we set a new model. This causes several emissions of
GtkTreeSelection::changed, for each of which we do a bunch
of work to update the path bar, the location entry, etc.

We can savely ignore some of these signals, and do less work.
