Roundtable drops any signatures that is not specified by `mustBeSignedBy`

It does any signatures that is not in mustBeSignedBy list. I'm not sure if this is an intended behavior or not, however, it confused me for few good minutes.

Confirmed - signed transaction with collateral input from wallet but without standard input was not processed properly - signature dropped

I believe that is not supported. Do you have a TX URL to test on? @SeungheonOh @przembot

It's more or less any transaction, but I think it's intended behavior not to add unspecified signatures(as it would change tx hash)
