Bug #72663 - part 1

Don't call __destruct() on an unserialized object that has a
__wakeup() method if either
a) unserialization of its properties fails or
b) the __wakeup() call fails (e.g. by throwing).

This basically treats __wakeup() as a form of constructor and
aligns us with the usual behavior that if the constructor call
fails the destructor should not be called.

The security aspect here is that people use __wakeup() to prevent
unserialization of objects with dangerous __destruct() methods,
but this is ineffective if __destruct() can still be called while
__wakeup() was skipped.
