guix-package: Gracefully handle multiple installs of the same path.
* guix-package.in (guix-package)[process-actions]: Compute PACKAGES such
that packages listed in INSTALL* are first removed from the remainder
of the list. When PROF is equal to the previous profile's store path,
do nothing. Reported by Andreas Enge <andreas@enge.fr>.
* tests/guix-package.sh: Test the behavior of installing the same store
path twice. When removing a package, omit its version number.
