datastore: load and save elements behind interfaces

Previously we didn't consider elements that
could be behind an interface field e.g.

   type Foo struct {
        Bar interface{}
   }

   &Foo{
        Bar: "bar",
   }

which would produce:

    datastore: unsupported struct field type: interface {}

We now extract the underlying element, during both
Loads and Saves.

Fixes #1474
