Tests occasionally (??) do nothing

[galexv]

Often, but not every time, running make test on Cloudbees under Jenkins results in:

ERROR: Step ‘Publish JUnit test result report’ failed: None of the test reports contained any result
[...]
Finished: FAILURE

and indeed, looking into the test log shows

Hmm any thoughts on why this is? Could it be due to the fact we use a new gtest compilation for each test file? I think somewhere in ALPSCore it was figured out how to only do it once, I should probably port that over as well

I don't have a good feeling for it. But for the supported open source codes, we could move to Travis CI instead (we're going to do this for Hiroshi's code, too). What do you think?

I forgot to reference it here, but in commit d0108da I added a Travis CI script
