CallMethod with ActionFieldFunctions does not compile

DROOLS-3893 [Guided Decision Table] Call method on is not generated - Red Hat Issue Tracker

The DROOLS-3893 needs an additional fix for Call methods setups where the CallMethod uses ActionFieldFunctions.

The problem appears when there is ActionCallMethod in a BRL before Set or Update column that is not BRL. The two columns use the same fact variable, so when searching by name the ActionCallMethod is found and we try to append the set/update to that. We should just ignore the call.
