Update test_combined_open_ended.py

This test fails even though the routine properly removes the inserted "onerror="eval()".  The test string (iframe_clean) has the same fields but in a different order as the input (iframe_dirty) string.  The fix is to change the test string (iframe_clean) to match the order of the input test string, minus the field that should be removed.  It now passes.
This test was failing due to invalid test data.  The code properly
strips the onerror="eval()" but the validation does not match the
result.  The reason is that the fields are in the wrong order.  The fix
was to correct the string to match the input string minus the field that
would be removed.  It will now pass.
