py3: fix exception in pull when several things happen to a bookmark

Specifically, when `changes` is:

  [(b'@upstream-committed', None, <function ui.status>, b'updating bookmark @upstream-committed\n'),
   (b'@upstream-committed', binary-node, <function ui.warn>, b'divergent bookmark @ stored as @upstream-committed\n')]

sorting the list raises:

  TypeError: '<' not supported between instances of 'bytes' and 'NoneType'
