Bump src/uaa

Update `cf-registrar` gem in `cf-registrar-bundle-for-identity`

* This makes the version of `cf-registrar` we use be 1.0.1 everywhere, so we
  get consistent support for clustered nats.

* 1.0.1 does failover in clusters correctly; 1.0.0 does not.

Bump cloudfoundry/uaa:
  James Myers:
     Remove `cf-registrar` call from uaa init as it's already in a separate job ( Travis created: https://travis-ci.org/cloudfoundry/uaa/builds/23085165 )
