Narrative network does not accept corpus widget, only import documents widget

[ThijsVroegh]

The narrative network, useful for extracting svo tuples, currently does not accept textual input read via the corpus widget (i.e. ,tab format), but only accepts input read via the 'import documents widget' (i.e. stories stored indiviudally in for example word documents).

[sgobyn]

It is not only the narrative network that does not accept textual input via the corpus widget. Running the actions and actors widgets when using the corpus widget is not working either.
