    appchooserwidget: Don't limit application list unconditionally
    
    As documented, GtkAppChooser is "typically [used] for the purpose of
    opening a file". However given that applications that support neither
    opening files nor URLs are filtered out, the chooser is not actual
    useful for any other (atypical) usage. Change that by only applying
    the filtering if a content-type was set, and use the full unfiltered
    list otherwise.
