[rules-users] modify and update is not working in the rule file

[Wolfgang Laun]

The cancellation of an activation and the ensuing call to
activationCancelled() is NOT sufficient as an indication of the rule
not matching your fact data.

Scenario 1:
   - fact(s) inserted
   - activation created from rule R1
   - fireAllRules
   - activation of rule R1 fired

Scenario 2:
   - fact(s) inserted
   - activation created from rule R1
   - fireAllRules
   - fact(s) inserted/created/updated (due to another rule firing before R1)
   - activation from rule R1 cancelled

Scenario 3:
   - fact(s) inserted
   - fireAllRules
   - nothing happens
