Use dont_preserve_original_methods and order_matters together for ClassBuilderStaticClass yields unexpected result

Here is an example that illustrates the issue:

shmock_class(
'Box_Helper_URL',
function (
$shmock
/** @var Box_Helper_URL|\Shmock\ClassBuilderStaticClass $shmock */
) {
// Keep track of the order of calls made on this mock.
$shmock->order_matters();
// Mock all methods, return null by default unless overwritten by the expectations below.
$shmock->dont_preserve_original_methods();
$shmock->disable_original_constructor();

$mock = $shmock->url_is_box('ab.com');
/** @var $mock \Shmock\Spec */
$mock->return_value(true);
}
);
\Statics::overwrite('Box_Helper_URL', $mockBox_Helper_URL0);

// Execute the method under test.

$objectUnderTest = new \StaticsUsageExample();
$executionResult = $objectUnderTest->isBoxUrl('ab.com');

// Validate the execution result.

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

}
}

The test failed. The url_is_box call on the mock object returned null instead of true as I expected.
#

Here is my analysis of the issue:

This is what I found that caused the failure:

dont_preserve_original_methods calls $this->__call($method->getName(), [])->any()->return_null();
to overwrite the static method calls of the class being mocked.

This has the same effect as specifying
$shmock->url_is_box()->any()->return_value(null);
in the mock object expectations.

Since order_matter is set, in effect the expectation becomes that url_is_box will be called once first and return null and it should be called again and this time return true.

This effect is not what I expected. And there is no documentation that I can find that describes this behavior.

The non static class builder has a different implementation and doesn't seem to exhibit this behavior.
