Merge pull request #4940 from RosettaCommons/vmullig/fix_hbond_counting_in_simple_cycpep_predict
Fix hydrogen bond reporting at the end of simple_cycpep_predict. I managed to break this in pull request #4702 by forgetting that my hydrogen bond counts were no longer negative numbers. This also adds a unit test confirming that another piece of needed functionality functions (though it turned out not to be the culprit).
