req.connection.address is not a function

[jguepin]

I am using the bugsnag error middleware to report errors with Express.
The middleware makes serverless-http crash, as req.connection.address() is not defined.

Maybe serverless-http could implement this method, as other Express/Connect middlewares probably use it?

See bugsnag/bugsnag-node#129 for details about the error.

Looks like you already added defensive code for this but I stubbed address() as of 1.5.4 -- not sure if it's properly stubbed, but the port is there (hardcoded to 443).
