Allow Android videos to be shown in the CameraRoll selector 

Summary:
Currently, Android camera roll videos cannot be retrieved in RN since

1) `CameraRollManager.java` doesn't do anything with the `assetType` param
2) Unspecifying MIME types doesn't show videos

This diff allows videos to be shown in the `CameraRoll.getPhotos(..)` call by reading `assetType`. Future diffs will come where the thumbnail and other info will be returned as well.
