RepositoryRestConfigurer are again used in declared order.

4b36f79 introduced a regression by consuming registered RepositoryRestConfigurer instances via ApplicationContext.getBeansOfType(…).values() which, unlike the previous consumption via a List<RRC> in an @Bean method, is losing the declared order of the RRC instances as ….getBeansOfType() is a Map.

We now rather use an ObjectProvider and its ….orderedStream() method to consume the registered instances ordered properly.

Fixes #1995.
