VIVO-774 When merging property lists, distinguish faux property from its base.

Merging list of populated properties with all possible properties,
   we don't want to consider two properties equivalent just on the basis of base URI and label (domainPublic)
Why was this previously considered to be a good thing?
VIVO-774 Fix display of unpopulated properties

Unpopulated properties with no domain URI were not recognized as faux properties
Use the faux property display name instead of the base property name.
