Passing query params breaks route in local

[atomaka]

When using chalice local, a route will not match if parameters are passed via the query string.

Given:

from chalice import Chalice

app = Chalice(app_name='web')

@app.route('/')
def index():
    name = app.current_request.query_params.get('name')
    return {'hello': name}

Running chalice local and then visiting http://localhost:8000/?name=test will result in ERR_EMPTY_RESPONSE with an error tracing back to raise ValueError("No matching route found for: %s" % url).

Running chalice deploy and then visiting the provided URL functions as expected and will return {"hello": "test"}.
