Bug 38257: Do not use js_includes.inc in two different files

Downloading cart didn't work because js_includes.inc file
was included both in basket.tt and intranet-bottom.inc.
This patch removes related codeline from basket.tt.

To test:
1. Search for items and add one or more search results to your cart.
2. Open cart.
3. Attempt to download items from your cart.
=> Either nothing happens.
4. Apply this patch, restart services if needed.
5. Again attempt to download.
=> Download menu should now work as expected.
