Test: extra debugging for refresh listeners stats 

This test failed in CI but didn't give us enough information to
debug it:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+nfs/223/consoleFull

This turns on more debugging and make the test fail more quickly
if something is obviously wrong.
