Build issues testing multi-apps projects

I've reworked how the multi-apps projects are built. In particular
I've made sure the test build is made from the top-level once, and
then only tests are run on this build. It used to build multiple
times and some builds would not include test mode, not good. I've
also fixed issues with running tests in parallel.

All tests now pass with -j8 on my machine. It's possible more
issues remain that are not covered by tests yet though.
