VIVO-82 Fix the creation of short-term models.

Browse source 
In the previous version of ModelAccess, all of the language-aware models were wrapped around their counterparts from the Context, so they did not come from the ShortTermRDFService. Fix it so any model that is not memory-mapped is built from the ShortTermRDFService.
