Apikey working for wrap_view and wrap_form urls

The apikey authentication wasn't working because several reasons:

 * The Authentication methods order, ReadOnlyAuthentication should be the
   last one because it override others.
 * The wrap_view and wrap_form were not calling the is_authenticated method
   which fills the request.user.

This thread in stackoverflow helps me to fix this issue:
