Don't rely on absolute position of <testsuite>s
Don't rely on absolute position of <testsuite>s

This adds a findSuite() function to the JUnit reporter tests to find a
<testsuite> element with a given ID attribute within the main
<testsuites> element. This is because the position of each element
within the <testsuites> element's array of children will no longer
correspond to the ID when we add a <properties> element.
