I expected this to only have two candidates because both globs are in the same scope, so panic candidates should only exist in two scopes total and it should tiebreak to the prelude candidate.

this handles the case where we're firing on two globs where neither is from the implicit prelude import (the glob vs multiouter test) and turning it into a hard error. We probably want this to be a warning but I think the tiebreak logic as I wrote it may be broken in this case and depend on import expansion order.
