  - Fix the verdict of TC in sub-testcase list result

    When the sub-test case list is defined, in the dovetail results,
    each test case is appeared with the its verdict next to its name.
    Once a sub-testcase is passed, the verdict PASS is appeared next
    to the name of sub testcase.
    Once a sub-testcase is skipped or failed, the verdict FAIL is
    appeared next to the name of sub-testcase.

    This fix updates the code so that the verdict of skipped and failed
    sub test cases to be appeared respectively next to its sub-tsetcase
    name.
