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

[cs278]

#227 broke backwards compatibility with tests written for prior versions of the module.

The following test now fails:

$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:

module-symfony/src/Codeception/Module/Symfony/RouterAssertionsTrait.php

Line 87 in 01cfa3e

* $I->seeCurrentRouteIs('posts.show', ['id' => 8]);
