Legacy settings tests fail while CUIT adapter is not adapted

When removing CUIT from vstest these tests were failing because we are using VS that has older version of CUIT still present, but VSTest has none of the components for CUIT (coded UI tests).

So to merge we had to disable the tests. Re-enable them after CUIT is removed from VS and we can consume that version of VS.
