patch

Basically, the adding of features comes from an existing plugin calling
gst_element_register(), so if the plugin is not there, it can't have
registered any features, so it does not make sense to remove them
when removing the plugin.

In the case where (on Windows) a plugin DLL have changed name, the loaded
features of the newly loaded plugin will be removed when removing the features
of the cached plugin.
