    Fix: Patch Remove Order

    When we remove a patch, we want the patch removal order to be
    such that the patch with the highest dependency is removed first.
    For example:
    P2 requires P1
    P3 requires P2
    P4 requires P3
    Removal order: [P4, P3, P2, P1]
    Since P4 has the highest dependencies (P3, P2, P1) followed by
    P3 (P2, P1) followed by P2 (P1) and P1 (None).

    Test Plan:
    Tested different scenarios with unit test cases
