fix: re-initialize resumable upload URL on each retry attempt

The resumable upload URL returned by Google Play is session-specific and
expires after a failed attempt. Retrying with the same URL always fails.
Also broadens the caught exception from HTTPError to RequestException so
timeouts and connection errors are retried too.
