The error "The requested resource cannot be found" is thrown when switching the "annotated" view for different files

Refer to FSH-3526

Consider I am viewing the "annotated" page for a file (let's call it "allan"), it's the latest revision of that file.
If I click on any other file (let's call it "zoidberg") on the left, fisheye may present me the same revision number of zoidberg like it did with allan. But that makes not much sense in my eyes, as

• two files having the same revision will most likely be caused by two different cvs-commits
• zoidberg may not have yet a revision as high as allan, "no such revision" will be raised
• even if zoidberg has a revision like allan does, it is most likely not the latest revision of zoidberg

My humble proposal: When in "Annotated" view, clicking on another file will always take you to the latest "annotated" revision of that other file
