Perspectives: Objects of wrong class can get added to wrong path via Copy/Paste or Cut/Paste

[BlackbitDevs]

Steps to reproduce:

1. Open "PIM" perspective on https://demo.pimcore.com/admin/?perspective=PIM
   It contains a custom view for Car objects on the left side and one for Category objects on the right side
   
2. Right-click category /products in the Categories custom view -> Cut
3. Right-click /aston martin on the Cars custom view and select "Paste > Paste cut-out element"

After pasting, the object is not visible in /aston martin in the Cars custom view. And it stays visible in the Categories custom view because this tree does not get refreshed.
After reloading Pimcore it is even worse: The object completely disappeared as it is not visible in the Cars custom view (because this custom view only shows objects of class Car) nor in the Categories custom view (because the object is in a different path now).

But when you switch to Default perspective, you will see that the object indeed got copied to /aston martin (or better /Product Data/Cars/aston martin):

We need to prevent pasting elements to custom views which do not allow the class name of the copied element.
