prefix "A" for Predicate in props_wrapper output

[kleinay]

Got this output from props_wrapper, for the sentence:
'Several people killed or injured in an explosion at a church in northern Nigeria , officials say .'

Notice a predicate named "A3".
This causes a bug downstream.

This may be caused by the coordination.
I'll take a look.
