Draw mode is not transitioning to simple_select on draw.create event

Nobody has claimed this yet.

**mapbox-gl-js version**: 0.45.0
**mapbox-gl-draw version**: 1.0.9

### Steps to Trigger Behavior

Use plunker below;
https://plnkr.co/x3R0TtHsNGzxPxAOL7HH

1. After map and draw tools load, draw a point
2. The `draw.create` event fires and console.logs the feature, and the current mode.
3. Try to set the mode to `draw_point` to continue drawing points (does not work)

### Expected Behavior
Based on the documentation - https://github.com/mapbox/mapbox-gl-draw/blob/master/docs/API.md#modes

Expect the `Draw.mode` to transition to `simple_select` and that you can change the mode back to `draw_point` to continue drawing points.

### Actual Behavior
The mode is still in `draw_point` and you can not draw another point.

Start with the linked Plunker and reproduce the draw.create flow using draw_point, then compare the observed mode with the modes behavior described in the API documentation. Trace the draw.create event and the draw_point/simple_select transition; done means a created point leaves draw_point and allows switching back to draw_point for another point.
