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'
