[bp/r45240][FIX] trackers: setFilter doesn't exist, replaceFilter seems to be the one

[FIX] trackers: Restore the "one" option functionality for ItemLink:displayOneItem, but make "multi" the default, as using "one" can cause unpredictable data changes (but it does mention "random")
Fixed in trunk in other ways in r45082 amongst others (thanks Bsfez and LPH)
