bookmark: do not crash when active bookmark is forward and --date is used
The logic that decides where to update according to the active bookmark
location (when not on ".") was setting the rev to update to before we process
--date. This lead to --date processing aborting because of duplicated
specification.
We reorder the two pieces of code and add a test for this.
