    Fix open location entry when pressing '~'
    
    Recent changes in GTK default input method
    makes ~ char to start as dead key, that's
    why filechooser stopped detecting it for the
    keybinding to open location entry.
    
    We also make sure '~' appears in the location
    entry (instead of being emtpy).
    
    Fixes #4911 for GTK3
