Copy or convert data to its own shallow copy leads to heap crash

[Wolfram Lyda]

The copy and the convertTo data use rhs.freeData() to free dest-data before copy / transform procedure. If rhs is already a shallow copy of the current field, itom crashed.

ToDo -> Check for shallow copy, modify code to avoid this problem.
