Previously, integrations could not be deleted. The view required a CSRF
token to be submitted but we were not sending one. Now we check for a
CSRF token field in the form before executing our HTTP DELETE request
and, if present, we add the X-CSRFToken header to the request. This
allows integrations to be deleted.

Able to delete an integration with this patch applied.
