Generic base view http_method_not_allowed method references self.request and should use locally scoped request

[Adam DePue]

The current method in django/views/generic/base.py is:

def http_method_not_allowed(self, request, *args, kwargs):

logger.warning('Method Not Allowed (%s): %s', request.method, request.path,

extra={

'status_code': 405,
'request': self.request

}

)
return http.HttpResponseNotAllowed(self._allowed_methods())

The 'extra' dictionary should reference the locally scoped 'request' object instead of the class scoped member.

There is a PR open with this fix:
​https://github.com/django/django/pull/2035

The side effect is that any unit test written that uses the view and manually calls the dispatch method to validate non-allowed-methods will crash with attribute not found error for request
