[Webtest] Patch for bug in com.canoo.webtest.reporting.XmlResultConverter

[Marc Guillemot]

Hi,

in com.canoo.webtest.reporting.XmlResultConverter.addParameters (line 166
for build 362)
instead of:
    String value = parameter.getValue() != null ? (String)
parameter.getValue() : "null";
use:
    String value = String.valueOf(parameter.getValue());

a parameter can be something else as a String (for instance a Boolean, which
produces an hard to catch bug as no stack trace get printed from
com.canoo.webtest.ant.TestSpecificationTask.report()). Furthermore is the
code cleaner.

Marc.
