RM-2937 - The destruction of records can not be completed if the metadata is set to be maintained after destruction.

- ExtendedContentDestructionComoponent uses the NodeService interface which enforces capability check. ExtendedContentDestructionComoponent  extends ContentDestructionComoponent from community which uses the nodeService implementation. I fixed it by using the implementation directly.
   - After fixing the issue I noticed the renditions nodes are not deleted which is a regression from 2.3 and there is no comment to specify this was intended so I deleted the rendition node.
