Issue Description

Hey,

I'm trying to mock a class method which has a new DateTime as default argument but it's not working. I get: Error: Undefined constant "DateTime".

Steps to Reproduce

<?php

declare(strict_types=1);

namespace Tests;

use DateTime;
use Mockery;
use PHPUnit\Framework\TestCase;

class HandlerClassTest extends TestCase
{
    public function testItDoesNotWork(): void
    {
        $class = Mockery::mock(MockClass::class)->shouldReceive('test')->with('test')->andReturn('yay')->getMock();

        self::assertSame('yay', (new HandlerClass())->doStuff($class));
    }
}

class MockClass
{
    public function test(string $a, DateTime $b = new DateTime()): string
    {
        return $a . ' - ' . $b->format('Y-m-d');
    }
}

class HandlerClass
{
    public function doStuff(MockClass $mockClass): string
    {
        return $mockClass->test('test');
    }
}

Additional Information

I found this PR #1160 but I think this did only work by accident? Or am I missing something? 😄

@jesperbeisner Thanks for reporting this issue.

I've identified the cause of this issue and am working on a patch now.

Mockery is currently generating the wrong code.

- public function test(string $a, \DateTime $b = DateTime): string {} // wrong
+ public function test(string $a, \DateTime $b = new DateTime): string {} // correct
