Fix controller sorting issue while loading large number of controllers #1180

This PR aims to solve the issue mentioned by @GilmarCorreia : #1170. With the tests, I'm able to reproduce the error at some number around 20 controllers, so in order to make it robust, I've added 2 more different tests, testing with around 200+ controllers and also trying to simulate complex chaining that could be in day-to-day use-cases.

I think we are missing the 30 additional controllers or I've missed it during review

Lol! You are right, let me reformulate it and add some more controllers for more complexity
