That was the intention when I made find_shared_symref() return struct
worktree * instead of char *. I forget why I changed my mind and not
do so. The only case when find_shared_symref should do this is when a
ref is shared twice, then we need to ignore current worktree from
inside the loop. But that can't happen. Will move this
ignore-current-worktree test to die_if_checked_out().
