Tever.reload receiving a viring.RegStateRecord rather than the expected Serder instance

[kentbull]

Problem

I am getting the following error because the Tever.reload function is expecting a Serder as noted in the docs for Tever yet it is receiving a viring.RegStateRecord dataclass object (as observed during a debug session).

This happens on GET to /registries for KERIA, yet it seems the issue belongs in this repository since the problem appears to be in the Tever class or eventing
