Properly handle promise rejection chains #70

Closed matthewp closed 8 years ago

This updates the Promise wrapping to properly handle rejection chains. If some code throws a string we should wrap it in an Error and rethrow it. This fixes a bug where System.imports that are rejected were not having their rejection bubble up.
