Bug 14399: Results form also needs a few interface changes

Currently, the value of compareinv2barcd is used to determine if the
Seen column, the Select/Clear all buttons and the Mark seen buttons are
displayed. But if we scanned barcodes, we already marked items as seen.
So we should only display these buttons when we did not upload barcodes.

Test plan:
[1] Upload a barcode file. Check that the result form does not show
    the buttons.
[2] Generate an inventory list, so do not upload a barcode file. Verify
    that you still see the buttons.
