test: update _invoke_tool dispatch assertion for new toolset-scope kwargs

The scoping fix added enabled_toolsets/disabled_toolsets to the
agent_runtime_helpers sequential dispatch into handle_function_call, so
test_invoke_tool_dispatches_to_handle_function_call's assert_called_once_with
(exact match) needs the two new kwargs. Both are None for the default agent
fixture.
