Continues from #1968

It already successfully detected couple of redefinitions, which in these cases meant couple of tests were in fact never run and it was overlooked before now despite them being worked on fairly recently.

Other than that I think sorting of imports is a nice change, but had to limit it due to the bittensor.synapse class/module hack (hopefully it can be removed in future).
