    Remove getRegion() calls from network initializers

    .init methods of the components are called before
    the environment is initialized. Thus regions are not
    configured at this point. Thus if the object is not
    directly or indirectly owned by the CloudRegion
    it cannot call getRegion() from the initializer.

    Normally networks do belong to CloudRegion
    so there is no problem. However a Network instance
    such as ExistingNetwork might be passed to the Instance
    class which is not owned by the ClouydRegion and in this
    case an exception will be thrown.
