Hi, the library is not working with PHPUnit 6.5 (phpunit-mock-objects 5).

<?php declare(strict_types=1);
namespace My;
use phpmock\phpunit\PHPMock;
class WillItWorkTest extends \PHPUnit\Framework\TestCase
{
 use PHPMock;
 public function testFoo(): void
 {
 $time = $this->getFunctionMock(__NAMESPACE__, 'time');
 }
}

Results in:

PHP Fatal error: Interface 'PHPUnit_Framework_MockObject_Matcher_Invocation' not found in /.../vendor/php-mock/php-mock-phpunit/classes/DefaultArgumentRemover.php on line 15

Version of relevant installed packages:
phpunit/phpunit 6.5.1
phpunit/phpunit-mock-objects 5.0.3
php-mock/php-mock 2.0.0
php-mock/php-mock-integration 2.0.0
php-mock/php-mock-phpunit 2.0.0

May be related to sebastianbergmann/phpunit-mock-objects#388 ?
