Update encodePlanAsJson for Installed package state

The change in how we use the PreExisting vs Installed states means that
we'll now have full details for all packages, rather than installed
ones having only the subset of info available from the
InstalledPackageInfo. So the 'type' field now can take the values
"pre-existing", "configured" or "installed".

Also do a little bit of tidying up.
