Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Don't allow user change SUT version to None after submitting

    We don't allow SUT version to be None when submitting test.
    So we also not allow user to change it to Nonw after submitting.

    In this patch, I also make the result table self-adaption.
