Fix aggregator _get_unique_key method

This patch fixes the error that occurs in aggregator when project_id and
user_id are missing from aggregated sample. This problem appears for
example when swift incoming/outgoing bytes samples are aggregated and
non-authenticated users access swift publicly readable containers.
