Crash while trying to write out reason for uncaughtException

[jrgm]

I noticed this in a logfile. I don't have steps to reproduce, but it did happen. I guess you need to check that e.stack at least exists, and if not then maybe just dump String(e) or something.

/data/fxa-auth-server/node_modules/mozlog/node_modules/intel/lib/record.js:24
      return e.stack.substr(e.stack.indexOf('\n'));
                                    ^
TypeError: Cannot call method 'indexOf' of undefined

Ah, ok. I worked out how to duplicate this in fxa stage. If the auth_db server is not up, then auth_server and email bouncer when they start get an error with no stack EndpointError: 127.0.0.1:8001 error: connect ECONNREFUSED.

Don't know why it has no stack, but it doesn't.
