Ensure final input of CommandTester works with default
If the final element of `CommandTester::setInputs()` is an empty string (to send the default value), the internal stream the tester uses hits EOF and triggers the `Aborted` exception. This appends an additional EOL to the stream after the `implode` to simulate one final return key, allowing the final input to use the default value when used in the tester's documented style.
