Fix a NULL pointer dereference when looking for a DESTROY method
The empty DESTROY method optimization introduced by commit
fbb3ee5af3d would crash the interpreter if a DESTROY method
was declared but not actually defined.
This is seen in the real world with AutoLoader / AutoSplit,
where the crash defeats autoloading a DESTROY method.
