When Lifecycle.dispose() is called, stop() may be skipped.

All of the GoovyNodeBuilderTestCases build the nanocontainer. (Which currently forces a start lifecycle to be called.)

But then at the end of the test, dispose() is called without calling stop().

If a container is started() when dispose() is called, then dispose() should call stop() before proceeding.

To me, it is conceivable that resources might be leaked otherwise.
