binarybeachio: trusted view — rename log extra key 'created' to 'is_signup'

LogRecord has a built-in `created` attribute (timestamp) and Python's
Logger.makeRecord raises KeyError("Attempt to overwrite 'created' in
LogRecord") when extra= contains it. The 500 fired AFTER user_login
already set the sessionid, so users were technically signed in but
saw a 500 page on first visit.
