Skolemize unstable prefixes in asSeenFrom
Skolemize unstable prefixes in asSeenFrom provided
- the prefix appears at least once in non-variant or contra-variant position
- we are in phase typer.
After typer, we have already established soundness, so there's no need to
do skolemization again. We can simply do the (otherwise unsound) substitution
from this-type to prefix.
