Fix Backbone session expiration specs
Fix Backbone session expiration specs

There was a typo in `before` block which caused the user login to
fail, which should have caused failing specs, but they succeeded.

Both the before block and the specs are now fixed.

There is also one spec added to specifically check the expiration
behavior of Backbone requests.
