Do not default to generate an UUID for namespaces if it is not
explicitly specified.
This is a technically a breaking change in behavior. However, since the
UUID changes on every VM launch, it is not spec compliant and is of
little use since the UUID cannot be used reliably anyway and the
behavior prior to this patch must be considered buggy.
