Final extra patch for the remaining crash problem

The direct cause of the crash is SdrObject.mpSvxShape points to a dangling
SvxShape object, while the weakreference SdrObject.maWeakUnoShape is correct. 
The root cause is in SvxShape::Notify(), it sometimes reset the pointer
SvxShape.mpObj without notifying SdrObject, then in SvxShape destructor it also
has no chance to notify SdrObject to reset the mpSvxShape to the SvxShape

But it is hard in SvxShape::Notify() to check if the SvxShape.mpObj->mpSvxShape
points back to SvxShape object itself, when the SvxShape object doesn't have
ownership to the SdrObject.  So the safe and quick fix still gets back to the
original workaround. I attach this final fix patch.

SdrObject.mpSvxShape is only for internal use. I guess it is for cache purpose,
so it needn't workout the real pointer to SvxShape object each time when it
wants to access it.  So I won't try to remove it now.
