Subject: [PATCH] Fixed \yiiunit\framework\helpers\JsonTest::testEncode() for
 PHP 5.4 (#19798)

* Fixed \yiiunit\framework\helpers\JsonTest::testEncode() for PHP 5.4

'\Generator' is only supported since PHP 5.5

* Actually fixed \yiiunit\framework\helpers\JsonTest::testEncode() for PHP 5.4

Turned out the test already failed during file parsing. Now using eval to "hide" the `yield`
