Constraints won't apply for views added in some specific order

[Mikhail Isaev aka iMike]

Steps to reproduce:

1. declare some view1
2. then declare view2 which have relative constraint to view1
3. add first view2, then view2

Result: relative constraint between view1 and view2 is not applied

Expected result: declared constraints should work as expected

Workaround:
First add view1 then view2
