TestPlanReference EnabledIf on Resource property

The Test Plan Reference step has an issue with resource properties that use EnabledIf. Upon connecting resources, a bogus warning gets logged, like this:

18:00:36.136  EnabledIf    Could not find property 'enableResource' on 'TestPlanReference'. EnabledIfAttribute can only refer to properties of the same class as the property it is decorating.

See attached test case to reproduce the warning.
