Nested testsuites in XML output are not parseable by Jenkins

[reid]

This is a regression in Grover 0.1.16.

Grover 0.1.16 introduced a change that causes additional <testsuites> tags to be nested inside the root <testsuites> tag.

Jenkins will only report tests in <testcase/> tags that are in nested in <testsuite> tags in the root <testsuites> tag. Nested <testsuites> are silently ignored. This comprises the majority of YUI's use of Grover.

(Examples can be found on the internal YUI dev-3.x component build. The regression occurred on build 240. The last correctly working use of Grover was on build 239. Compare the junit.xml artifacts on those builds.)

It appears the regression occurred in f5b1f91.

The YUITest.TestRunner.getResults("XML") method appears to return nested <testsuites> because of the change to the results object from data[key] to data[name][key] when results has length !== 1.

The same problem is doing the TAP files receive a wrong head ( first line ). All have 6 test suites with 122 tests, but it only shows 2 tests.
