DATACOUCH-432 - Fix ANSI Joins OneToOne relationships

Browse Source 
Couchbase template could get only the component type information which
works for collection properties but when the join is one-to-one for a
single generic type it would fail. The fix is use to the actual type if
the property is not a collection.

Original PR: #177.
