peer: when collecting method names for batch calls, bytes-ify __name__

This will explode violently if we have a non-ascii command name. That
shouldn't ever happen in core, and seems unlikely even in third-party
code. Regardless, it'll explode violently, so we can revisit things in
the future if we need to change the encoding here.
