bookmarks: fix head selection for merge with two bookmarked heads

A type mismatch caused the search for the other head to fail. The code is
fragile, and instead it ended up using the 'first' bookmark head, but the
ordering is undefined and it could thus randomly use the wrong bookmarkhead
and fail with:

  $ hg up -q -C e@diverged
  $ hg merge
  abort: merging with a working directory ancestor has no effect

  $ . "$TESTDIR/histedit-helpers.sh"

Ensure hidden revision does not prevent histedit
-------------------------------------------------

create an hidden revision

  $ cat > commands.txt <<EOF

check hidden revision are ignored (6 have hidden children 7 and 8)

  $ cat > commands.txt <<EOF

Check that histedit respect phases
