Steps to reproduce

1. Activate staging local with blogs and document library
2. Import two files A and B
3. Create a Blog entry and link it with files A and B
4. Publish to live
5. Check AssetLink table at both staging and live: two links from blog to dl will exist (A and B)
6. Edit blog entry and remove link with B
7. Check AssetLink table at staging: only one link from blog to dl will exist (A)
8. Publish to live
9. Check AssetLink table at live:
   • Wrong behavior: two link from blog to dl will exist (A and B)
   • Expected behavior: live environment will have same information than staging environment
