fix: dont omit license from stored manifests (#7475)

This has the effect of adding licenses back into the lockfiles.
Based on code in shrinkwrap.js and inventory.js, it appears that
lockfiles are supposed to store the license. It's likely that in
practice this behavior has not been consistent due to fetching
of minifed manifests and packuments.

I also attempted to remove the license code from shrinkwrap but
that caused many more tests to break. Plus I believe this is the
intended behavior, to have licenses in lockfiles based on bug
reports like #7384
