function RulesTriggerTestCase::testRecursionOnDifferentArguments

Tests recursion prevention with altered arguments.

Ensure the recursion prevention still allows the rule to trigger again during evaluation of the same event set, if the event isn't caused by the rule itself - thus we won't run in an infinite loop.
