addmultisigaddress creates an address respecting the setting, being unable to generate a specific type of address without also adding it to the wallet seems wrong.

I suppose in the future `addresstype` may be refactored to be wallet-specific, which would leave this non-wallet rpc call without an argument. Perhaps there should just be an optional parameter to set it.
{
    assert(pwallet->GetBroadcastTransactions());
    if (!IsCoinBase() && !isAbandoned() && GetDepthInMainChain() == 0)
    {
        CValidationState state;
        
        if (InMempool() || AcceptToMemoryPool(maxTxFee, state)) {
            LogPrintf("Relaying wtx %s\n", GetHash().ToString());
            if (connman) {
                CInv inv(MSG_TX, GetHash());
                connman->ForEachNode([&inv](CNode* pnode)
                {
                    pnode->PushInventory(inv);
                });
                return true;
            }
        }
    }
    return false;
}
