    tests/utils.py: add one more test cases for bb.utils.vercmp_string
    * this is just another test case for issue already fixed in:

        Subject: bitbake: fix version comparison when one of the versions ends in .
    * The TypeError is triggered not by '.' at the end, but from the extra
      numberic component in one of the versions.
    * When one version has fewer elements, it's extended by another (0, None)
      element where 0 means numeric component. Then the result cannot be
      decided by comparing the types (oa < ob, ob > oa) and it continues
      to compare values (ca < cb) which fails when one of them is the None
      from (0, None) appended before.
