* Remove redundant python2 support code `str.decode()` doesn't exist on python3, so presumably this code was doing nothing * Filter out pushers with corrupt data When we get a row with unparsable json, drop the row, rather than returning a row with null `data`, which will then cause an explosion later on. * Improve logging when we can't start a pusher Log the ID to help us understand the problem * Make email pusher setup more robust We know we'll have a `data` member, since that comes from the database. What we *don't* know is if that is a dict, and if that has a `brand` member, and if that member is a string.
