    ("package with properties"): New test

Hi again,

if I'm not mistaken, it is also required to (quasi)quote the value of
properties.  This patch updates package->code to achieve this.
Afterward, the following command:

> $ guix import json /dev/stdin <<EOF
> {
>   "name": "hello",
>   "version": "2.10",
>   "source": "mirror://gnu/hello/hello-2.10.tar.gz",
>   "build-system": "gnu",
>   "home-page": "https://www.gnu.org/software/hello/",
>   "synopsis": "Hello, GNU world: An example GNU package",
>   "description": "GNU Hello prints a greeting.",
>   "license": "GPL-3.0+",
>   "native-inputs": ["gettext"],
>   "properties": {
>    "hidden?": true,
>    "upstream-name": "hello-upstream"
>   }
> }
> EOF

should produce the following package definition:

> (define-public hello
>   (package
>     (name "hello")
>     (version "2.10")
>     (source (origin
>               (method url-fetch)
>               (uri (string-append "mirror://gnu/hello/hello-" version
>                                   ".tar.gz"))
>               (sha256
>                (base32
>                 "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i"))))
>     (properties `((upstream-name . "hello-upstream") (hidden? . #t)))
>     (build-system (@ (guix build-system gnu) gnu-build-system))
>     (native-inputs (list (@ (gnu packages gettext) gnu-gettext)))
>     (home-page "https://www.gnu.org/software/hello/")
>     (synopsis "Hello, GNU world: An example GNU package")
>     (description "GNU Hello prints a greeting.")
>     (license license:gpl3+)))
> hello
