ECMS-6036: Problems of content activity after deleting nodes

Problem analysis:
  - after moving a file to Trash, if there are many files with the same name, there will be an index in the file's suffix.
  - However, when we get such value, we do not use the index.

Fix description:
  - Use node's UUID to avoid getting the wrong node
