xunit reporter does not report <testcase />
currently Xunit reporter only reports the top

```
<testsuite name="Mocha Tests" tests="16" failures="0" errors="0" skipped="0" timestamp="Fri, 04 Sep 2015 23:05:49 GMT" time="0.043">`
```

but not the child test cases
something that i would expect is:

```
<testsuite name="Mocha Tests" tests="16" failures="0" errors="0" skipped="0" timestamp="Fri, 04 Sep 2015 23:35:14 GMT" time="0.043">
  <testcase classname="case1" name="abc" time="0.2"/>
  <testcase classname="case2" name="cde" time="0.1"/>
</testsuite>
```

is there a reason for it?


quite possible it's broken since we don't have good tests for the reporters

yep. since i upgraded mocha from 2.2.4 to 2.3.0.

using:

```
--reporter xunit --reporter-options output=build/testreport-integration.xml
```

only writes the first line:

```
<testsuite name="Mocha Tests" tests="242" failures="0" errors="0" skipped="21" timestamp="Fri, 04 Sep 2015 18:55:09 GMT" time="25.353">
```

Just to help confirm this.

Stupid simple test file

```
> cat test.js
describe('my test', function() {
    it('should pass', function(done) {
        done();
    });

    it('should fail', function(done) {
        done(new Error('fail'));
    });
});
```

Works as expected in `2.2.5`

```
> mocha --version
2.2.5

> mocha --reporter=xunit test.js
<testsuite name="Mocha Tests" tests="2" failures="1" errors="1" skipped="0" timestamp="Wed, 09 Sep 2015 18:29:50 GMT" time="0.006">
<testcase classname="my test" name="should pass" time="0.001"/>
<testcase classname="my test" name="should fail" time="0"><failure><![CDATA[fail
Error: fail
    at Context.&lt;anonymous&gt; (test.js:7:8)]]></failure></testcase>
</testsuite>

> mocha --reporter=xunit --reporter-options output=results.xml test.js; cat results.xml
<testsuite name="Mocha Tests" tests="2" failures="1" errors="1" skipped="0" timestamp="Wed, 09 Sep 2015 18:29:56 GMT" time="0.007">

```

But not `2.3.0`

```

2.3.0
