update: update to current bookmark if it moved out from under us (issue3682)

If the current bookmark (the one listed in .hg/bookmarks.current)
doesn't point to a parent of the working directory, e.g. if it was moved
by a pull, use that as the update target instead of the tipmost
descendent.

A small predicate is (finally) added to the bookmarks module to check
whether the current bookmark is also active.
