Where qz-tray factory is an object not a function

Loading the ember app in a browser results in the following error

    TypeError: this.callback.apply is not a function[Learn More]

    Module.prototype.exports  loader.js:106
    Module.prototype._reify   loader.js:143
    Module.prototype.reify    loader.js:130
    Module.prototype.exports  loader.js:104
    requireModule             loader.js:27
    <anonymous>               app-boot.js:3

Editing the qz-tray lib to use a factory function rather then factory
object allows the app to load.

Looking at https://github.com/amdjs/amdjs-api/blob/master/AMD.md#factory-
a function or object should be allowed.
