Path to the configuration file missing in the status verbose output

When running framework tests in verbose mode, in some places the command of the test is returned.
Unfortunately, sometimes it doesn't contain a path to the xml configuration file
e.g. see below. The path to the file should be between "-c" and "--filter"

```
RUN TEST FILE: cd /home/vagrant/dev/hhvm/hphp/test/frameworks/framework_downloads/typo3/typo3/sysext/core/Build && export TYPO3_PATH_WEB="/home/vagrant/dev/hhvm/hphp/test/frameworks/framework_downloads/typo3" && /home/vagrant/dev/hhvm/hphp/test/frameworks/../../hhvm/hhvm -v Repo.Local.Mode=-- -v Repo.Central.Path=/tmp/framework-testw1vYu6 --config /home/vagrant/dev/hhvm/hphp/test/frameworks/php.ini /home/vagrant/dev/hhvm/hphp/test/frameworks/framework_class_overrides/../framework_downloads/typo3/bin/phpunit --debug -c --filter 'TYPO3\\CMS\\Core\\Tests\\Unit\\Utility\\GeneralUtilityTest::formatSizeTranslatesBytesToHigherOrderRepresentation with data set "Label for gigabytes can be exchanged"'
```

I found out that the path is not included when outputing the data from line 238, and 222 of Runner.php

However the config file is present correctly at the beginning of the output
e.g.

```
Beginning the unit tests.....
Command: export TYPO3_PATH_WEB="/home/vagrant/dev/hhvm/hphp/test/frameworks/framework_downloads/typo3" && /home/vagrant/dev/hhvm/hphp/test/frameworks/../../hhvm/hhvm -v Repo.Local.Mode=-- -v Repo.Central.Path=/tmp/framework-testw1vYu6 --config /home/vagrant/dev/hhvm/hphp/test/frameworks/php.ini /home/vagrant/dev/hhvm/hphp/test/frameworks/framework_class_overrides/../framework_downloads/typo3/bin/phpunit --debug -c /home/vagrant/dev/hhvm/hphp/test/frameworks/framework_downloads/typo3/typo3/sysext/core/Build/HHVMUnitTests.xml 2>&1
```

and also after I placed debug message at the beginning of getTestRunStr()

```
verbose("Command2: ".$this->actual_test_command."\n");
```

I've got correct results every time.
