Previously, transformations applied from a manifest (rather than via "guix install") would be lost. This change fixes that and simplifies things. Reported by zimoun at <https://lists.gnu.org/archive/html/guix-devel/2021-02/msg00153.html>. * guix/profiles.scm (default-properties): New procedure. (package->manifest-entry): Use it for #:properties. * guix/scripts/pack.scm (guix-pack)[with-transformations]: Remove. Remove caller. * guix/scripts/package.scm (transaction-upgrade-entry): Remove calls to 'manifest-entry-with-transformations'. * tests/guix-package.sh: Add test. * tests/transformations.scm ("options->transformation + package->manifest-entry"): New test.
