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.
You're right, it looks like it should have been removed after https://github.com/ibm-js/delite/commit/70d83ada8831d4107a8331a64d938a0f6bb9ff12. I'll check the code coverage report to make sure and then I'll update the source code.
Thanks.
