Remove node-uuid

We currently install `uuid` and `node-uuid`. `node-uuid` is deprecated
in favor of `uuid`. It seems like we already switched a while ago, but
somehow missed to remove the dependency.

This patch does exactly that. It removes the dependency from
`package.json` and this way removes the warning during install about
`node-uuid` being deprecated.
