Revert the check of the route name

Let's revert #5853 until we can fix the bugs reported in:

* 8e35082#commitcomment-123618904
* #5864

`@inalbilal` I want to fix the bug that you originally reported in #5853, but I think we'll need to use a different fix because some people reported exceptions after applying this change in their applications. Thanks.
