Bug 546700 - Nested LeafConditions - value changes do not always trigger
refresh

* Fix the IterateConditionService to also return the iterate conditions
item reference in #getDomainModelReferences. This is necessary to
correctly re-evaluate the iterate condition's rule when a value
referenced by the item condition changes.
* Added a RCPTT test for this
* Adapted the iterate condition plugin test

Furthermore, fixes the condition reference service strategy providers
for iterate, lead, and rule dmrs.
