This patch fixes runtime attaching to an ASAN-enabled QiTissue.

I can only explain this by assuming that the list got mutated while
iterating over it, i.e. basically a recursion of `objectAdded` which
could happen when we init the factory?

The operator= was not correctly implemented and would have
deleted the dptr under the wrong situations. This lead to either
crashes or leaks, depending on the usage. The new test e.g. would
crash in ASAN like this:
```
