EventEx state machines persist on a pico across uninstalling and reinstalling associated rulesets

Given this example rule

  rule testEventExStateMachine {
    select when test pre_reinstall before
                test post_reinstall
    send_directive("Rule was selected and run");
  }

If the pico is sent test:pre_reinstall then the ruleset is uninstalled, then installed again, sending test:post_reinstall will select on the rule.
I even restarted the engine between uninstalling and installing the same ruleset again and the rule still selected on test:post_reinstall when test:pre_reinstall had been triggered.

I am fairly positive this is unwanted behavior as it could cause weird bugs in code between differing installations of the same ruleset on the same pico.

I first encountered this behavior with the group operator count <int>

Start by tracing EventEx state-machine state through the ruleset uninstall and reinstall lifecycle, including an engine restart. Reproduce the sequence with test:pre_reinstall and test:post_reinstall, then check the count group operator case. Done means state from the previous installation no longer selects rules after reinstall.
