Support for refactored login token handling

loginToken handling is now done by the session loader, so we need to pass in
the queryparams to MatrixChat.

Also, MatrixChat no longer automatically reloads the page to drop the
querystring, so we have to do that ourselves (doing it in index.js allows
tokenlogin to be tested).
