Backwards compatibility break in `RouterAssertionsTrait::seeCurrentRouteIs()`

https://github.com/Codeception/module-symfony/pull/227 broke backwards compatibility with tests written for prior versions of the module.

The following test now fails:

```php
$I->seeCurrentRouteIs('some_route', [
'id' => 1,
]);
```

With:

```
- Expected | + Actual
@@ @@
Array &0 [
'_route' => 'some_route',
- 'id' => 1,
+ 'id' => '1',
]
```

This usage is even how the method is documented:
