screen.lua: dump payload on handler failure

For debugging failures like:

    test/functional/helpers.lua:240: test/functional/ui/screen.lua:898:
    bad argument #1 to 'unpack' (table expected, got number)

    test/functional/helpers.lua:240: test/functional/ui/screen.lua:708:
    attempt to index local 'item' (a number value)

ref #10804
