    Avoid using whitespace in test_safe_parse_xml.

    Updates our MiscellaneousXMLUtilTests.test_safe_parse_xml test
    so that it avoids using and ignores whitespace. This works around some
    minidom parsing differences that can happen with some versions of python
    2.6.

    Fixes LP Bug #1158826.
