[AUH][PATCH v2 2/9] upgrade-helper.py: Handle fetch errors gracefully during version scan

From: Daniel Turull <[email protected]>

Materialise the iterator from get_recipe_upgrade_status into a list,
catching any exception that terminates the iterator early. A single
unreachable upstream (e.g. git.savannah.gnu.org down) no longer
aborts the entire scan — the recipes collected so far are still
processed.
