TestSetterAndGetterTrait: Allow setting target per individual test

[TiSiE]

This feature let's you use a different SUT for an individual test.

public function setterAndGetterData()
{
   private $target = SubjectUnderTest::class;

    return [
        ['id', 'someTestId'],
        ['test', [
            'target' => SpecialSubjectUnderTest::class,
            'value' => 'test',
        ]],
    ];
}

Also: The trait throws only InvalidUsageExceptions.
