Fix Automation validation for void,void document(s),document(s) operations

When dropping some operations into the Automation panel, validation is applied to warn users if operations signatures are compliant.

Between void,void and document(s),document(s) operations, validation is not applied correctly, doesn't warn the user the compliance issue. Whereas for void, void and blob(s),blob(s), the validation is working well.

We should fix this validation for the first use case.
