Tests update: parserTests sha, blackist, local copy of html2wt tests

* We have additional test failures:
  - Some tests in parserTests.txt changed from disabled --> parsoid
    which were failing Parsoid tests before parserTests.js started
	respecting the 'disabled' flag.

* A couple of html2wt-centric tests fail in wt2html and html2html
  modes after new test snippets were added there.

* Several new html2wt tests now pass after parserTests.txt was updated
  to reflect latest Parsoid output.
