Fix guidFor import

[villander]

its fixes #298

// this works
import { guidFor } from '../utils/computed';
guidFor(whatever);

// and this works
import * as customComputed from '../utils/computed';
customComputed.guidFor(whatever);

// but this does not work.
import customComputed from '../utils/computed';
customComputed.guidFor(whatever);

This is a case where ember-cli historically allows a non-spec-compliant behavior.
