Bookmarks: Improve behavior of "Previous Bookmark"

If the text cursor is currently not at the "current bookmark", it is
more intuitive and useful if "Previous Bookmark" first moves to the
current bookmark, instead of jumping to the one before that.
That solves two issues:
- creating a bookmark, jumping somewhere else, and then going back to
  that bookmark
- deleting a bookmark, and then going to the previous one
