v0.2.16.2: deterministic names when loading from config

Version 0.2.16.2:

Bug fix/Improvement

• Makes component name property for the default composites deterministic instead
  of random uuid, now also working when loading a dashboard .from_config()
  • note however that for custom ExplainerComponents the user is still responsible
    for making sure that all subcomponents get assigned a deterministic
    name (otherwise random uuid names get assigned at dashboard start,
    which might differ across nodes in e.g. docker swarm deployments)
• Calling self.register_components() no longer necessary.
