Fix contact saddle-point preconditioner tests

These tests target the contact preconditioner, thus their nonlinear
solver tolerance is way to loose. Hence, results are affected by changes
in the subdomain. Slightly loosening the result tolerances makes the
test more robust.

Number of linear iterations have changed as well.
