The Entity.add_property method now checks whether the name of an added property matches a special attribute and, if so, updates the attribute instead.
Addresses #217
Focus
Should similar behaviour be supported for updates using only id? If so, how would I go about finding out which id the name attribute/property has server-side?
As the method is called add_property and special attributes do not support multi-properties (as far as I know?), should we guard against an overwrite by only setting the attribute if it is currently None?
