--stop-on-failure does not work with WrapperRunner

[willemstuursma]

--stop-on-failure doesn't do anything when running with WrapperRunner.

Here is some output from our CI environment:

TEST_DATABASE=xxxxxx_test_ php -dxdebug.profiler_enable=0 -dxdebug.cli_color=1 -dxdebug.coverage_enable=0 -ddisplay_errors=stderr vendor/bin/paratest --colors --runner WrapperRunner --processes 8 --stop-on-failure --configuration tests/phpunit.xml

.............................................................  488 / 4865 ( 10%)

As you can see, it dutifully labours on even after the failure.

Seeing the same issue here. I even passthru --stop-on-error --stop-on-defect --stop-on-failure to PHPUnit but that makes no difference.
