[DependencyInjection] remove missing-service suggestions

This is a rollback of 729db0fde: a change which introduced a significant performance penalty for little gain. During normal use of ContainerBuilder, levenshtein() is called many times each time a service is requested for the first time. In a container with just 20 services, for example, this will result in 400 calls to levenshtein(). That's a significant performance hit which only serves to provide some convenience for the comparatively rare situation when a developer asks for a truly non-existent service.
