Fix problem with initialization order in `ClassToAPI.scala`.
Fix problem with initialization order in `ClassToAPI.scala`.

In `ClassToAPI` both `Private` and `Protected` vals had forward
reference to `Unqualified` so they would get `null` as a result.
Fixed that by rearranging the order of vals being declared.

This fixes a problem described in 9dd5f076ea3d3c1cca257a548646c4807e58879a.
