Stub out pkgState with non-error, helps with debugging.
Summary:
When we use -dppr-debug, we'll sometimes attempt to
hit the pkgState to give more detailed information. It's pretty
annoying to have this fail because we haven't filled in the
pkgState: we can still get useful debugging information by
printing the raw package key. To avoid this, we just put
in some empty stub pkgState, to be filled in later.
