Setting dont_preserve_original_methods interferes with mocking __call methods

[HappyRay]

e.g.

class MagicMethodTest
{
    /**
     * @param string $methodName
     * @param array  $argument
     *
     * @return string
     */
    public function __call($methodName, array $argument)
    {
        return $methodName;
    }
}

class MagicMethodUsage
{
    /**
     * @param \Box\PHPUnitTestGenerator\tests\_fixture\_input\MagicMethodTest $magicTest
     *
     * @return string
     */
    public function callMagicMethod(
        MagicMethodTest $magicTest
    )
    {
        $rc = $magicTest->foo();

        return $rc;
    }
}

<?php

class MagicMethodUsageGenTest extends \PHPUnit_Framework_TestCase
{
    use \Shmock\Shmockers;

    public function testCallMagicMethod()
    {
        // Setup mocks for parameters to the method under test.

        $mockMagicMethodTest0 = $this->shmock(
            'MagicMethodTest',
            function (
                $shmock
            ) {
//                $shmock->dont_preserve_original_methods();

                /** @var $mock \Shmock\Spec */
                $mock = $shmock->__call('foo', array (
                ));
                $mock->return_value('bar');
            }
        );

        // Execute the method under test.

        $objectUnderTest = new MagicMethodUsage();
        $executionResult = $objectUnderTest->callMagicMethod($mockMagicMethodTest0);

        // Validate the execution result.

        $expected = 'bar';
        $this->assertSame(
            $expected,
            $executionResult,
            'Variable ( executionResult ) doesn\'t have the expected value.'
        );
    }
