Remove exact option from selectors in specs

The :exact option only has an effect on queries using the XPath#is
method, and just raises a warning otherwise. I've verified that these
tests do fail if the text is not in the expected plural form. As the
:exact option not having any effect on this test, we don't need it, and
can remove it.
