Prop 855: IBC Client Update: Expired Client to Realio Chain

Due to an unforeseen relayer issue that resulted in the subject client exceeding the trusting period, the IBC client 07-tendermint-1157 used by channel-726 for ATOM transfers from Cosmoshub to Realio is currently in an expired state. If accepted, this proposal will update client 07-tendermint-1157 with the data from 07-tendermint-1189 which is created newly, so that users may continue to take advantage of both the established channels.
