Cancel Subscription fails

[reillychase]

Issue Summary

Trying to cancel a subscription results in no error message displayed to user, but subscription is not deleted.

Debug

Cancel subscription debug (there doesn't seem to be any error when actually pressing cancel, but there is an error when the 'are you sure you want to cancel' page is loaded), not sure if relevant:

Exception while resolving variable 'errors' in template 'pinax/stripe/subscription_delete.html'.
Traceback (most recent call last):
  File "/home/rchase/hostifinetenv/lib/python3.6/site-packages/django/template/base.py", line 835, in _resolve_lookup

    raise KeyError(key)
KeyError: 'errors'

Was that a result of clicking "cancel" ?
