List is now using the last dstore version instead of using dstore 1.0.

This PR depends on https://github.com/ibm-js/delite/pull/270.
It fixes both https://github.com/ibm-js/deliteful/issues/253 and
https://github.com/ibm-js/deliteful/issues/65.
Is that function used somewhere? I don't see it being called by anything? Am I missing something?
