executeList returns an empty slice when the chain has no rule at the given id, but ListById indexed rule[0] unconditionally and panicked with index-out-of-range. Return a descriptive error instead so callers can recover. Closes coreos#130 Signed-off-by: Charlie Tonneslan <cst0520@gmail.com>

Closes #130.
`executeList` returns an empty slice when the chain has no rule at the given id, but `ListById` indexed `rule[0]` unconditionally and panicked with index-out-of-range. Surface a descriptive error instead so callers can handle the case.
