[FIX] payment_authorize: use name to send values when partner is a company

Currently, the name's fields to send to Authorize when the partner is a company are:

* firstName
* lastName

if we consider following name `Company Duck Inc`:

the code is sending:

* firstName: ''
* lastName: 'Duck'

Only it sends the `lastName` with the second word found in the name,
due to the new validations in Authorize.Net, this kind of transactions
are marked as suspicious and it's not confirming the transactions, leave them
as pending, this commit is sending the full name in `lastName`
instead of only second word to meet with the validation in Authorize.Net

Also, we are sending the fields `firstName` and  `lastName`, with the
maximum length allowed by Authorize.
