Fix in glm2, there was an nee when redirected to glm model view cause model is not in KV store yet. Fixed.
Fix in MRTask2. Futures (_fs field on MRTask2) did not get passed in the clone, resulting in them being null for forked MRTask instances and introducing potential race (not wanting for DKV.puts to finish).

Made _fs to be shared on local node (it's transient so remotes don't matter).
