Updated RecordsRead to return RecordsDelete and initial RecordsWrite when record is deleted

[thehenrytsai]

Prior to this change, a 404 status is returned without any data when a RecordsRead is performed against a deleted record.

But 404 status alone prevents a the RecordsDelete from being imported into the caller's DWN for the purpose updating the record's state.

This PR updated RecordsRead to return RecordsDelete and initial RecordsWrite when record is deleted.
