AutoTest: Fix adding finish message into results tree

For QTest based tests we added the function finish message wrongly
to the last data tag when using data driven tests.
Not crucial, but it would become so in a follow up.
For finish messages we know that these only apply to test functions
or cases - never data tags.
This patch ensures we only add TestEnd messages to the corresponding
TestStart.
