Florian Müllner 923d926345 st: Remove invalid introspection annotation
(optional) is only valid for (out) or (inout) parameters (that are
marked as such).

However GError** arguments appear as throws="1" in the GIR anyway
instead of an explicit parameter, so we don't need any annotation
at all here.
