[cmd] Store command should print deduplicated statistics

Previously the store command printed the raw statistics of the report
folder, but none of the other commands or result of actions (parse
command or the result of the store) reflected these numbers.
This patch fixes that, and now the store commands prints the same
summary as the parse command.
