[PATCH 2/3] remote-hg: allow invalid bookmarks in a few edge cases

[Max Horn <max@quendi.de>]

Fix the previous commit to workaround issues with edge cases: Specifically,
remote-hg inserts a fake 'master' branch, unless the cloned hg repository
already contains a 'master' bookmark. If that 'master' bookmark happens
to reference the 'null' commit, the preceding fix ignores it. This
would leave us in an inconsistent state. Avoid this by NOT ignoring
null bookmarks named 'master' or 'default' under suitable circumstances.
