runfix: reduce number of calls to getSubconversation

[PatrykBuniX]

Reduce a number of calls to getSubconversation endpoint. Previously we were using the endpoint to get the fresh list of conversation members. Currently we use corecrypto.getClientIds to get the list of members we send to AVS via setEpochInfo. This way we're sure we update avs with the state we really have not what we get from backend.
