don't show NO_PUBKEY warning if repo is signed by another key
Daniel Kahn Gillmor highlights in the bugreport that security isn't improving by having the user import additional keys – especially as importing keys securely is hard. The bugreport was initially about dropping the warning to a notice, but in given the previously mentioned observation and the fact that we weren't printing a warning (or a notice) for expired or revoked keys providing a signature we drop it completely as the code to display a message if this was the only key is in another path – and is considered critical. Closes: 618445
