Does this mean that the tests in this repo aren't being flake8'd by travis but they are in the main repo?

Seems to be the case since omero-test-infra doesn't copy the script tests:

/opt/omero-test-infra $cat scripts-copy
#!/bin/bash

set -e
set -u
set -x

rm -rf $OMERO_DIST/lib/scripts/omero

cd $TARGET
cp -r omero $OMERO_DIST/lib/scripts/
