[Bug] Query.decode_parameters() does not return dictionary

[sophokles73]

Describe the bug

The Query.decode_parameters() method is supposed to return a dictionary containing the parameters passed in via the query string. However, when trying to get a parameter from the returned object, an exception is thrown, indicating that the object has no attribute get.

IMHO this line in the Query class should read

return super().decode_parameters()

To reproduce

1. register a Queryable with a handler.
2. In the handler, try to decode the parameters using Query.decode_parameters().
3. Try to invoke dict.get(key) on the returned object.
