Title: Fix a bug of `coffee-engine` if the option to make coffeescript source maps is disabled

If the option to make coffeescript source maps is disabled, Mincer compiles any coffeescript code in an empty javascript code.
It is because that the coffee engine assign to `context.data` the `js` property of the result of `coffee.compile` which is `String` type if the option is disabled.
