Justin S 6f1fe3904c Fix outdated R packages failing to fetch (#11039) ... PR #10758 made a slight change to find_versions_of_archive() which included archive_url in the search process. While this fixed `spack create` and `spack checksum` missing command-line arguments, it caused `spack install` to prefer those URLs over those it found in the scrape process. As a result, the package url was treated as a list_url causing all R packages to stop fetching once the package was updated on CRAN. This patch is more selective about including the archive_url in the remote versions, explicitly overriding it with matching versions found by the scraper.		2019-04-19 17:39:13 -07:00
