Upgrade StorageIssue: merged item is related to itself
I noticed an issue in Zotero 5.0.85: Merging two related items creates an item that is related to itself.
Steps to reproduce:
1. Relate two items.
2. Merge the two items.
3. Empty the trash. (This is not needed.)
4. Check the related items for the merged item. It's related to itself.
After I noticed the issue in my library, I reproduced it with all add-ons disabled. For the test, I used "Add item by identifier" twice with the same DOI and changed the titles to '1' and '2'. Then I followed the steps above.
This issue should not be critical, since one can simply remove the item from the list of related items.
