Synchronize Query Parameters Between ServerRequest and Uri

[butschster]

Within the FakeHttp class, developers can specify query strings in two ways:

1. By embedding them directly in the URI:

$http->get('/some-uri/?foo=bar');

2. By passing them as an associative array:

$http->get('/some-uri', ['foo' => 'bar']);

This flexibility, however, can lead to potential inconsistencies when both methods are used simultaneously. It's crucial to ensure coherency between the query parameters of the Psr\Http\Message\UriInterface class and the Psr\Http\Message\ServerRequestInterface class.

This PR modifies the createRequest method of the FakeHttp class to address this inconsistency:

• It first checks if the Uri in ServerRequest has any query parameters.
• If found, these parameters are merged with the ones provided to the createRequest method, ensuring a comprehensive and consistent set of query parameters.
