fix(query): add default parameter initializer

[seriouslag]

This PR adds a default parameter initializer if all the properties of the object are optional.

This is an ease-of-use feature that improves DX.

Fixes: Default empty arguments #37

  // if the props tags and limit are optional (using props)
  const { data, error, refetch } = useDefaultServiceFindPets({ tags, limit });
  // before this PR, we would have to pass an object to the hook (not using props)
  const { data, error, refetch } = useDefaultServiceFindPets({});
  // with this PR, we no longer are required to pass an object if all the props are optional (not using props)
  const { data, error, refetch }  = useDefaultServiceFindPets();
