We've hit a situation where a project (pycadf) is listed and capped
in stable/icehouse requirements.txt. pycadf is also listed in
projects.txt. As part of the requirements integration test, we are
attempting to update pycadf's master branch with stable/icehouse
requirements, and failing because of new dependencies in pycadf that
are not managed by stable/icehouse's GR.
This updates integration.sh so that when we're testing a stable branch,
we are only syncing requirements to other projects have stable branches.
This avoids trying to sync stable requirements into library's master
branches.
