Fix failed testRandom assertion

[peter279k]

Changed log

• Fix Arrays::random method test.
• The first parameter is in PHPUnit\Framework\TestCase::assertContains method should be specific value. The Array::random method will return the array type with one value and we have to get that value and pass to the first parameter in assertContains method.
• It's related to issue #223.
