Merge pull request #5463 from RosettaCommons/roccomoretti/fix_test_residue_summary_metric
Fix test_residue_summary_metric for individual running.
The SimpleMetricTests:test_residue_summary_metric was relying on other test functions in the class for setting up the pose.
While this happened to work for Suite running, if you ran just the single test, then it failed.
Adjust it to properly set up the pose, independent of the other tests in the class.
