[gnome-boxes] i-props-provider: String change always succeeds

    i-props-provider: String change always succeeds
    
    We are no longer watching for failures in change of an editable string
    property and none of the users of this API makes use of this functionality
    anyway so no reason for EditableStringProperty.changed() to return
    boolean.
