DB/Misc: Misc Fixes

* Fix an error with spellfocus with previous conditions
* Battle for Hilsbrad so previous quest links to correct quest and not one which is disabled as depreciated quest,  ie quest 14351 replaced quest 550 but tc still had quest 550 set as next quest quest for 541 and was missing creature_queststarter entry for correct quest
* Crusader Bridenbrad phasing (should be visible for a tale of valor)
