LogoutTimer not being cleared correctly

[wnxhaja]

I recently upgraded my feathers authentication from v1.2.2 to v1.2.4.

I am calling app.authenticate() on my client and expecting for the jwt expiry to update. I get the updated jwt token with the new expiry. But still I am being logout by the server because jwt token expires.

I look up the changelog and I found this fix #449. It is now using long-timeout in setting the logoutTimer but still using the old way of clearing timeout here. Then I change to lt.clearTimeout(logoutTimer) and it is now properly clearing the timeouts.
