tests: add test case for rule replacement expression deactivation
When a rule is replaced, all of the expressions that are in use need to be deactivated. Kernel missed to do this on replace. In this example, this would result in a leak of the chain use counter ("jump" expression deactivation is not called). This then either resulted in a BUG or WARN, depending on kernel version.
