Remove subject.name from subject topic facet but keep combined value on show page

[orangewolf]

User Story:
As of right now, the subject.name and subject.topic fields are merged. As such, the values for subject.name are showing up on the "Topic" facet alongside those of subject.topic. Is there a way we can have them merged on the item page, but omit the values of subject.name from the facet? Or if it applies to one, does it have to apply to both? If that is the case, we will probably want to separate them upon the implementation of the new fields. In any case, I have reflected this desired change on the sheet as well.
