Code Issues Proposed changes

Remove unused context parameter from db.archive_deleted_rows* methods

Browse Source 
Commit 316a94dd03 removed the usage of
the @require_admin_context decorator from the DB API methods and the
context parameter was only used for that decorator, so we can remove
the context parameter now.
