Changed logout routes to POST instead of GET

Browse Source 
As per #3047.

Also made some SAML specific fixes:
- IDP initiated login was broken due to forced default session value.
  Double checked against OneLogin lib docs that this reverted logic was fine.
- Changed how the saml login flow works to use 'withoutMiddleware' on
  the route instead of hacking out the session driver. This was due to
  the array driver (previously used for the hack) no longer being
  considered non-persistent.
