4348	Validator wrongly merge duplicated nodes.	Zibik	team	"Simple test scenario:

1. I download any area from OSM and create a node.
2. I send the node to JOSM (and the node has assigned ID)
3. I select this node and copy it (CTRL + C)
4. I create a new layer and paste this node here (CTRL + V)
5. I merge both layers together.
6. At this point, I have a duplicated node.
7. I check by validator, it detects a duplicated node.
8. I click on Fix.
9. Validator removes the node with assigned ID and replace it with a new (without ID)
10. JOSM wants to upload the new node.

The problem is trivial for a single node, but it looks otherwise  when I prepare import and I have several thousand duplicated nodes.
Do not want to unnecessarily spam OSM database.
