Fix another DOM test that had broken expectations for the number of results.

The input XML file looks something like this:
   <foo> <a></a> <b></b> &c; </foo>
The &c; entity expands to <c></c> on the RI. On Android, it is ignored. That
behavior is known.

The results from the RI were 3 elements:
   <a> <b> <c>

The results from Android were also 3 elements, but a different 3:
   <foo> <a> <b>

With my recent fix, the result is what it should be for a system that doesn't
expand entities:
   <a> <b>

I've adjusted the test to expect one fewer element. It now fails on the RI,
because we're not expecting the expanded entity.
