When copying a folder that contains project with downstream/upstream projects, the upstream project points to the old folder.

How to reproduce:

1. Create new Folder -> "myfolder"
2. Create new freestyle project -> "project1"
3. Create new freestyle project -> "project2"
4. project2 -> Build after other projects are built -> Projects to watch -> myfolder/project1
5. Copy myfolder -> otherfolder

Actual results:
"otherfolder/project2" upstream project is "myfolder/project1"

Expected results:
"otherfolder/project2" upstream project should be "otherfolder/project1"
