Already deleted Message returns 404 vs 409 conflict when a 2nd attempt to delete is processed

[LiranCohen]

After merging #635, which was a bit old, one of the new tests failed upon merge to main.

During a dwn-sdk-js change the return for a conflicting RecordsDelete changed from a 409 to a 404.

This PR addresses it within the new record.delete() method, as well as for sync, adding additional coverage.
