Remove test for QS and QQS constraints

New versions of ConstraintLayout can optimize the constraint set. In this test we were asserting that two constraintsSets were the same despite being specified in different ways (in different xmls).

version 2.2.0-beta05 ended up optimizing some constraints, making the test fail, despite no (apparent) visual differences.
