Cleanup duplicate getter setter in Document

In the class org.nuxeo.client.api.objects.Document, two pairs of getter / setter methods are duplicate:

• First pair
  • getPropertyValue(String)
  • setPropertyValue(String, Object)
• Second pair
  • get(String)
  • set(String, Object)

These pairs have identical logic inside the method. However, the decision of cleanup should take account of the origin of theses methods and why we should or should not keep them.
