Title: Resolve destinationRoot in prepCopy.

This improves the configurability of generator subclasses with non-standard `destinationRoot`s.

Currently, `prepCopy` resolves the `source` argument against the Generator's configurable `sourceRoot`. This commit adds the same behaviour to `destination` and `destinationRoot`, respectively.
