Different namespaces used for memcache and datastore

[luna-duclos]

If ctx and key have a different namespace for any kind of request in nds, then nds will use the key's namespace for the datastore request, as intended, but will do the memcache requests without creating a new context with that namespace in it, causing the memcache requests to be against a different namespace

Just pulled this and tested, my unit tests pass now, ty! :)

@PSG-Luna just to let you know that I found an edge case bug with my namespace fix and have updated the repo with a fix b6608fb.
