Brakes doesn't work with service calls that are arrow functions

[Alex Wolden]

const Brakes = require('brakes');

const prom = (foo) => {
    return new Promise((resolve, reject) => {
        resolve(foo);
    });
}

const brake = new Brakes(prom);

brake.exec('foo').then(result => {
    console.log(result)
}, err => {
    console.error(err);
});

Causes the following error:

./node_modules/brakes/node_modules/promisify-node/utils/args.js:9
  var args = func.toString().match(/function\s.*?\(([^)]*)\)/)[1];
                                                              ^

This seems to be caused by reflection that promisify-node is doing under the covers to detect meta data about the passed in function.
