When encountering an unrecoverable IO error during pre-execution-phase work use the more appropriate and correct ExecutorInitException than ViewCreationException. Importantly, note that ExecutorInitException will give us the right exit code and since it's a subclass of AbruptExitException we get the right build status codes too.
