looper report runs pipestat summarize multiple times

[donaldcampbelljr]

I noticed in the refactored hello looper examples that looper report seems to call pipestat summarize multiple times (seemingly once per sample):

(venv) drc@databio:~/GITHUB/hello_looper/hello_looper/pipestat_example$ looper report --portable

Using looper config (.looper.yaml).

It should be iterating over each pipeline interface.
