Query parameters are not handled the same way than on the delivery / production side

See https://github.com/adobe/helix-cli#passing-request-parameters.

In our Fastly magic, the query params are filtered out for caching reasons. You can enable them via the params property on the strain (see https://github.com/adobe/helix-cli#passing-request-parameters). This is not respected in the simulator, you can pass and use in the pre.js any request parameter.
