Fix the issue of publishing from web API without reviewers or groups specified.
Review Request #9210 — Created Sept. 23, 2017 and submitted — Latest diff uploaded
When creating a new review request with no reviewer or groups
assigned, attempting to publish it with PUT will be sucessful.
However, it shouldn't allow that as review requests must have a
reviewer. The issue is solved by adding conditions to validate the
review draft on the server.
Added a unit test, which passes (along with all other tests).
- Created a draft test review that don't have a reviewer/group name.
- Ran it using this command ./tests/runtests.py
- This will raise a publishingError since there isn't reviewer.
- Fixed other unit tests that failed because of the change.
