[libpeas] Free the registered extension impls when the object module is unloaded

[Garrett Regier <gregier src gnome org>]

commit 5751032b551aa19e6d75dde4332b0dfaeaa2f708

    Free the registered extension impls when the object module is unloaded
    
    When the object module is reloaded they will all be added again as
    peas_register_types() will be called.
    
    This caused problems when checking if the interface was already
    registered as it was always already registered when reloading the
    module.
