Update testing.yml

oops, trying to force it to build without the cache while a cache existed, made it try to build without a cache with files carried over from the cache, bad. Manually deleting the cache made it go back to standard behavior, meaning it tried to run both without and with cacheing function paths.

reverting back to standard cache function triggering, with manually deleted cache.

for issue #556
