Multisignature is still encoded through Amino and prefix is added when encoded to Amino pubkey, but the prefix was not modified for ostracon, so multisig pubkey was not encoded correctly.
Accordingly multisig address was not generated correctly.
The problem was solved by modifying the prefix to match the ostracon.
