Issue summary

micro-dev throws the following:

(node:29516) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'indexOf' of undefined

(node:29516) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 3)
(node:29516) PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 2)

From what I can tell this happens on the following line when a content-type is not sent in the header:
https://github.com/zeit/micro-dev/blob/7ea8ae05a56fa76788bed6fc9ee2d38728e0eac6/lib/log.js#L38

How to reproduced:

  1. Set a simple micro project
module.exports = () => 'Hello'
  1. Run it using micro-dev
  2. Send the following to localhost:3000 without setting a content-type header
POST http://localhost:3000/

{
  "test": "some-data"
}

You should see the above error in your console
