D7407: debugcommands: add assertions to convince pytype peer is not None

REVISION SUMMARY
  This function is moderately annoyingly defined, and peer is set up iff we're
  not in raw-proto mode. That's fine, but it confuses pytype. Adding these
  assertions is a low-overhead way to convince pytype we're doing reasonable
  things.
