AutoTest: Fix handling exceptions while environment setup

If setting up the environment for gtest fails due to an exception
we might end up having no reportable result but we get a return
code of 1 for the test application.
Inform the results pane instead of just ignoring the return code
and explicitly send a fatal result for this.
