D12406: histedit: remove an unnecessary default value of `b''` for commit message

REVISION SUMMARY
  I don't think `ctx.description()` is ever anything falsy other than
  `b''`. I think the comment added in 4c4232e51167 <https://phab.mercurial-scm.org/rHG4c4232e511677f06f684bdbf532bdc9e4adf5c9a> (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).
