[JENKINS-1258] error in schema testResult for Junittest #784

the schema for TestResult was added recently however there apears to be a bug in it.
the following lines appear to be invalid JAXB

line(74): <xsd:element name="status" type="hudson.tasks.junit.CaseResult$Status"
inOccurs="0"/>

and
line(96): <xsd:simpleType name="hudson.tasks.junit.CaseResult$Status">

also (likely as a result of this)
the api/xml looks like it had trouble:

<testResult>
<child/>
<child/>
..repeated a lot more
<child/>
<child/>
<failCount>38</failCount>
<passCount>774</passCount>
<skipCount>0</skipCount>
</testResult>
