Bug 30755: (follow-up) Add a results hash to automatic renewals

It's slightly debatable whether auto_too_soon is an error or not. I think
it leans far enough towards error that the other patch is correct. The change, however,
will affect notices and means we cannot count auto_too_soon anymore

This patch adds a new 'results' hash to the info - this includes a count per error
(including auto_renew i.e. success) allowing for notices to decide how to display the info.

To test:
1 - Add to Auto renew digest notice:
[% IF results %]
There were [% results.auto_too_soon %] items that were too soon.
[% END %]
2 - Check out some items to a patron that will be too soon
3 - Check out one that is not too soon and will renew
4 - Ensure patron has auto renew digest selected and that AutoRenewalNotices is set to follow patron preferences
5 - Run the auto renewals cron
6 - Confirm the notice for the patron displays 1 successful renewal, no failures, and a correct count of too_soon
