Update transaction_address to support name attribute

Solidus is moving away from using first_name and last_name, in favor of
just "name". This updates the paypal JS to send a name to
transaction_addess, rather than splitting it on the spot.
transaction_address is responsible for either:

* Splitting the name, if the user is on Solidus 2.10 or below
-or-
* Passing the name directly to the address, if the user is on Solidus
2.11 or higher - where the name parameter is supported.
