Fixes Android Release images not rendering (Issue #129) (#514)

* Fixes Android Release images not rendering (Issue #129) (#1)

* Fixes Android Release images not rendering (Issue #129)

Issue caused by 2 things:

- Image resources were not properly getting the path due to missing scheme (if required via require('./images/img.png'))
- markUpdated() was not causing a re-render thus image was not updating if it was a resource id after fetching. This is been changed to directly call bitmapTryRender, however, this may not be the best approach to this issue.

Minor note: After making this change, RenderableShadowNode would get a null for images. I put a null check for the alpha parameter to suppress this.

* Reverts check for color work around
