Fixing two issues in the accessibility CTS tests.

1. The filter used for matching a expected accessibility
   event was not cleared after a successful match, this
   cause the tests to break if rung more that once.

2. Updated the expeced class name for the first expected
   node info in the testTraverseWindow() tests since
   we now report only public classes i.e. the deepest
   framework class that the event/info source extends.
