histedit: remove an unnecessary default value of `b''` for commit message

I don't think `ctx.description()` is ever anything falsy other than
`b''`. I think the comment added in 4c4232e51167 (histedit: extract
common summary code into method, 2016-05-27) is mistaken (I don't see
any code following that pattern before the function was added).

# Dummy extension to define a namespace containing revision names


from mercurial import namespaces


def reposetup(ui, repo):
    names = {b'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: [b'r%d' % repo[node].rev()]

    ns = namespaces.namespace(
        b'revnames',
        templatename=b'revname',
        logname=b'revname',
        listnames=lambda r: names.keys(),
        namemap=namemap,
        nodemap=nodemap,
    )
    repo.names.addnamespace(ns)
