We're now gating on pep8, so make it pass. This removes a couple of
unused imports and fixes a typo in the CSV output code in the reviewers
The list of reviewers in the code actually includes people that didn't
do any reviews, but received them. Since tracking received reviews,
this value became inaccurate.
Remove the number of reviews received from the reviewers report output.
I think this information is valuable, but the values we're getting are
not accurate. The problem is that if a patch gets rebased, the trivial
rebase detection will automatically re-apply reviews. Those are getting
counted even though they aren't new reviews being received.
This involves updating one of the shell scripts which now depends on
'pip install -e .' or 'pip install reviewstats' (for a release) having
One step on a long path. Note that there is some noddy stuff in here
like a pointless test - its in cookiecutter and I don't want to muddle
code moves up with that, so 'meh'.
