[NP 405] Don't force author name initialization.

Re https://forums.zotero.org/discussion/32288/np-405/

I did obtain the NP 405 manuals. @adam3smith has access to them. If someone else wants access, let me (or @adam3smith) know.

Oh, I should say that section 6.2 of NP 405-1 says
>Podem ser utilizadas abreviaturas nos seguintes casos:
Nomes próprios de autores, editores literários, tradutores, etc., desde que fiquem
inequivocamente identificados.
Ex. PIAGET, J.

or as Google Translate would say...
>Abbreviations may be used in the following cases:
Proper names of authors, literary editors, translators, etc.., Provided it
unequivocally identified.
Eg Piaget, J.
