Update turbolinks 2.2.1 -> 2.2.2

Changes:

  Always use absolute URLs as cache keys and in state objects.
  Eliminates possibility of multiple cache objects for the same page.

  Allow periods in a link's query string (ex. /users?sort=account.email)
  without it interfering with the extension check.

  Don't process links with no href attribute.
