test(cutouts): keep the repeated-call determinism test, skipped on the open Fill defect

Restore RepeatedCallsReturnIdenticalPoses for a 1 x 1 square and a 1.5 x 0.75 rectangle.
Both cases fail intermittently because Default Fill can return different, equally scored
lattices for identical calls (Project Memory opennest c98c21bd), so they are skipped with
that reason until the defect is fixed rather than removed.
