Bug 36741: Skip auto_too_soon issues in auto renew digest

This change adds a line to skip auto_too_soon issues/checkouts
in the auto renew digest template.

Since auto_too_soon do not trigger notifications and don't require
any special action, let's skip them in the breakdown of checkouts in
the AUTO_RENEWALS_DGST email.

Test plan:
0. Apply the patch
1. reset_all (in koha-testing-docker)
2. Note the following line in the AUTO_RENEWALS_DGST template:
[% NEXT IF (checkout.auto_renew_error == 'auto_too_soon') %]
