Quickjump should list all bookmarks, not only those of current revision

[Jun Omae]

After #10527 and #11995, MercurialRepository.get_quickjump_entries(rev) lists only bookmarks for current revision. The method should list all bookmarks regardless of value of rev argument.

Suggestion from comment:5:ticket:11431.
