This method prevents excessive calls to the S3 API, creating a bucket
only if the store method fails with a NoSuchBucket error instead of
asking for the bucket before each request.

In my opinion, a permission error should not result in the entire
reprocessing job being terminated. Especially for large amounts of
files, it's to be expected one or two have various permission issues.

Instead of exiting, now simply print a warning to stderr.
