Title: Comparison of Matrix configurations done by Matrix Root Project

This is a tentative fix to make work both options "Throttle this project alone" and "Throttle Matrix configuration builds" together.

I don't know if this is completely correct, in my tests is working but I would like to get feedback before merging it and testing it thoroughly with all the possible combinations.
