Bug 20473: Don't display 'Item information' tab when adding to basket from a file and not creating items

This patch adds a conditional, and moves another up one level to remove the tab
when it will have no content/effect

To test:
1. Stage a MARC file from Tools > Stage MARC records for import
2. Go to Acquisitions and create a basket for a vendor
3. Add to basket from staged file
4. Note that the "item information" tab is present, if you click on it, not that it is not useful
5. Cancel adding to basket
6. Apply patch
7. Add to basket from the staged file again
8. Confirm there is no item information tab
9. Confirm orders are added on 'Save'
