bitbake: tests/utils.py: add one more test cases for bb.utils.vercmp_string

* this is just another test case for issue already fixed in:
    commit fef56d28c3efec4876c379898cbc4d4c65303aee

    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.
