Subject: [PATCH] gdbusmethodinvocation: Fix a leak on an early return path
When doing an early return from `g_dbus_method_invocation_return_*()`
due to passing in the wrong type (or no return value when one was
expected), the parameters were not correctly sunk and were leaked.
Fix that. A unit test will be added in a following commit.
