revision.c: better error reporting on ref from different worktrees
Make use of the new ref aliases to pass refs from another worktree around and access them from the current ref store instead. This does not change any functionality, but when a problem arises, we would like the reported messages to mention full ref aliases, like this: fatal: bad object worktrees/ztemp/HEAD warning: reflog of 'main-worktree/HEAD' references pruned commits instead of fatal: bad object HEAD warning: reflog of 'HEAD' references pruned commits which does not really tell where the refs are from.
