GetPrerequisites: Only recurse on resolved unseen prerequisites
I encountered an issue where not all prerequisites would be listed by
`get_prerequisites` since some of the prerequisites cannot be resolved
and are added to the list of unseen prerequisites. This has the side
effect of clearing the list of `prerequisites_var` and thus removes some
prerequisites from the list. Fix it.
