Title: Fix reduction bug with empty LocalArrays.

Reduce methods don't work nicely with empty local arrays. This raises a `NotImplementedError` when a reduction method is called on a distarray with empty localarrays.

This is merely a stopgap fix to prevent hangs and other horrible behavior before the 0.3 release. In coming refactorings, we will fix this properly.
