is_success and is_declined is broken

[chadwhitacre]

(Pdb) trans.is_success()
*** AttributeError: 'Transaction' object has no attribute 'processor_response'
(Pdb) trans.is_declined()
*** AttributeError: 'function' object has no attribute 'get'
(Pdb) 

The docstring for each says "You are better off checking trans.errors", which is good advice. Could these functions themselves be simplified to use trans.errors?

def is_success(self):
    return not self.is_declined()

def is_declined(self):
    return bool(self.errors)
