Fixed one of the failing tests for rules coverage:

- The test model didn't allow multiple values for the category property.
 - The setting of the category in the action puts a single value if one doesn't exist,
   or changes the value to a collection if a category already exists.  This is true even
   if the category is exactly the same.
I have **NOT** managed to fix the 'testInboundRuleType' because it would appear that the
test action evaluation is being done with a NoConditionEvaluator.  The test checks to
see that the action is not executed for an empty content node.  It might be a side-effect
of the parent node update policy ... but I can't see why.
