This doesn't have to do with your email directly.

But on the topic of tests, org 9.0.8 will fail 2 tests on emacs master. The
fix is already in org maint branch, post 9.0.8:
http://orgmode.org/cgit.cgi/org-mode.git/commit/?h=maint&id=3bcfed071deca0e9c5e8dd298b28bfd5903c6f9a

Just saying in case someone comes across those 2 test failures:

   FAILED  test-org/custom-properties
   FAILED  test-org/forward-paragraph

So do not worry about those 2 as they will be fixed after the next minor
release of org.
