Fix incorrect redirect protocol used by Flask
Flask's `request.url` uses `http` as the protocol, which breaks
instances that enforce `https`, since the session redirect relies on
`request.url` for the follow-through URL.

This introduces a new method for determining the correct URL to use for
these redirects by automatically replacing the protocol with `https` if
the `HTTPS_ONLY` env var is set for that instance.
