reachablePositions in event.metadata is empty (2.7.0)

[lajanugen]

I recently upgraded to 2.7.0 and have some issues with the reachable positions variable in event metadata - it seems to be empty. Issues can be reproduced as follows,

import ai2thor.controller
controller = ai2thor.controller.Controller()
e = controller.step('GetReachablePositions')
assert e.metadata['reachablePositions'] == []

Hey, please use actionReturn instead of reachablePositions for now. Using reachablePositions will probably throw an exception soon.

With PR #628 reachablePositions is remapped to actionReturn. Closing issue as it appears to be resolved.
