fix/test #1762 Excluding failing tests from campaign

The following tests are now excluded from the test campaign because they
often fail (those tests should be rewritten in a more reliable way):

on Firefox 3:
 test.aria.utils.HistoryTestCase on Firefox 3
on IE 11 with JAWS:
 test.aria.widgets.wai.errorlist.binding.ErrorListBindingJawsTestCase

close #1762
