Logout with wrapped token

[zofskeez]

This fix addresses an issue with the wrapped_token query parameter not working with the logout route. The user was presented with the login form rather than attempting to unwrap the supplied token and login automatically.

What happens if you have a namespace with a query param for a wrapped token?

[zofskeez]

Looking at the auth-form component, if wrappedToken is provided it will automatically attempt to unseal the token and if successful it preforms the same action as if the form has been filled out and the user hits submit manually. If a namespace is present in the query param it should behave as if the user selected one in the dropdown.

Also, is this a good candidate to add some test coverage for this scenario? Also does this need to be backported? I added the 1.10 release milestone as it's a bug. Not sure if this means we need to backport this to 1.10 or not because it's not rc-1.

I had a look and there were already Acceptance tests covering this, wrapped-token-test.js and redirect-to-test.js. I think the reason this wasn't caught is because of the check for the testing environment and then using replaceWith instead of location.assign. In the case of using replaceWith the query params from the transition are preserved. See #12035 for how this came about.
