Inconsistency in root level element in JUnit format

[bryanbcook]

It appears that there are several different implementations of the JUnit xml format. The root element is either a <testsuites> that contains a collection of <testsuite> elements, or a single <testsuite>.

As per bryanbcook/azdevops-testplan-extension#16, there appears to be two conflicting schemas:

• https://github.com/testmoapp/junitxml - defines <testsuites> as a root node. This is the format used by the testparser project
• https://github.com/windyroad/JUnit-Schema/blob/master/JUnit.xsd - referenced by IBM's website defines an xml schema that supports either <testsuites> or <testsuite> as the root node.

There is also an issue in this repo for #40 which doesn't have any details.
