Make checkIsMyInvitation use Django to parse the URL
Using django is more reliable and makes the code easier to read as
there is no knowledge of the url layout required.

The below HTML code was generated and appended by Google. It's purpose is
to display a logging console in the browser. It's appearing here because
either:
(a) the CGI parameter "debug" was in the URL
(b) the cookie "_ah_severity" was present in the HTTP request
To stop this from being appended, you should remove the CGI parameter
"debug" from the request URL and then either click the "Close" link on the
logging console, or delete the "_ah_severity" cookie.
All element ids used by the code for this logging console are prefixed
with "_ah", all cookies used are prefixed with "_ah", and all classes and
functions are in the namespace "AH".
