Validation error for missing bufferView in sparse accessors

[elrnv]

When validating a GLTF file with a sparse accessor that intentionally omits a bufferView, the spec permits this, however the validator complains:

A sample file can be found here: https://github.com/elrnv/gltfgen/raw/master/assets/tet_and_tri_expected.glb

You should probably raise this issue with the glTF-Validator and not here. @lexaknyazev

@bghgary Thank you! I raised the issue with glTF-Validator.
