fix obscure bug in callpoint class that triggered db integrity errors

Callpoint class had a placeholder attribute original_calls
which was initialized as an empty dictionary,
and thus was usable. Class __init__() code did not initialize
original_calls as it should but because the placeholder was
usable it did not break. Alas, the placeholder is global
to all subclasses and their instances and one instance
leaked attributes and functionality to the other.

This caused the kamaki quotaholder client to be hijacked
and directly call the backend, which was available
on the same system/gunicorn deployment in our tests.
The backend was directly called from an astakos view that
had no transaction active (i.e. was on auto-commit).
Normally, the backend would be called from the
quotaholder_app view, which explicitly sets up a transaction.
