Matthias Clasen 08e25b9ef7 app chooser: Avoid duplicates 
At the time we populate the model "initially" in constructed(),
it has already been filled and cleared a couple of times (we do
that every time one of the construct properties gets set). So
we can't assume that the model is empty, and have to clear it
first. Otherwise, we add duplicates to the list.

/**
* SECTION:gtkappchooserwidget
* @Title: GtkAppChooserWidget
* @Short_description: Application chooser widget that can be embedded in other widgets
*
* #GtkAppChooserWidget is a widget for selecting applications.
* It is the main building block for #GtkAppChooserDialog. Most
* applications only need to use the latter; but you can use
* this widget as part of a larger widget if you have special needs.
*
* #GtkAppChooserWidget offers detailed control over what applications
* are shown, using the
* #GtkAppChooserWidget:show-default,
* #GtkAppChooserWidget:show-recommended,
* #GtkAppChooserWidget:show-fallback,
* #GtkAppChooserWidget:show-other and
* #GtkAppChooserWidget:show-all
* properties. See the #GtkAppChooser documentation for more information
* about these groups of applications.
*
* To keep track of the selected application, use the
* #GtkAppChooserWidget::application-selected and #GtkAppChooserWidget::application-activated signals.
