Steps to reproduce

1. Create a new site
2. Create a document into Document Library, called DocumentA
3. Export site to a LAR file
4. Rename document to DocumentB
5. Create another document into Document Library, called DocumentA
6. Import LAR file to site with document with old name (DocumentA)
   • Wrong behavior: During document import, "DocumentB" cannot renamed to "DocumentA" due name collision and a duplicate exception is thrown. LAR is not imported
   • Expected behavior: During document import, due of name collision with existing "DocumentA", "DocumentB" is renamed into "DocumentA 1". LAR is successfully imported
