import: cran: Robustify cran-package?.
* guix/import/cran.scm (package->upstream-name): Return #f if url start and end index could not be determined. (cran-package?): Check if the upstream-name can be extracted from given package. * tests/cran.scm: Add "r-minimal is not a cran package" to make sure that r-minimal is not detected as a cran package. This fixes a failure of guix refresh on r-minimal because no upsteam-name can be determined from ".../R-version.tar.gz" uri.
