fix(storage/local): also put deduped blobs in cache, not just origin blobs
this caused an error when trying to delete deduped blobs
from multiple repositories
fix(storage/s3): check blob is present in cache before deleting
this is an edge case where dedupe is false but cacheDriver is not nil
(because in s3 we open the cache.db if storage find it in rootDir)
it caused an error when trying to delete blobs uploaded with dedupe false
