Upgraded lodash to 4+

[odino]

Hola people!

Was playing around with grpc on node and realized it requires an older version of lodash -- in the spirit of keeping everything updated I'm sending this.

• package.json is updated
• _.object became _.fromPairs (ref)

Ran npm test and everything seems fine -- let me know if any issue! :)

Thanks for the pull request, but this change is already part of the pending change in #7738.

WHAT''s the ETA for #7738 to make it to master? :)

Probably soon after it gets merged. And it shouldn't matter, exactly, because we publish from branches anyway.
