fix: fix copy of copied classes

[tikhanovichA]

https://oat-sa.atlassian.net/browse/ADF-1545

We need to fix the possibility of copying already copied classes.

How to test:

1. Go to items and create a new folder/class
2. Copy this class
3. Try to copy the folder you got in step 2

After switching to the new version cache should be deleted to generate a new DI cache
