configitems: do not directly match generic items Before this changesets, a literal '.*:foo$' config would match a registered '.*:foo$' generic. This is wrong since generic should be matched through regular exception only. This changeset fixes this problem. Thanks for to Yuya Nishihara for spotting the issue.

obsfate: fix obsfate_printer with empty date list When the list of dates is empty, `min` and `max` would raises a ValueError. Protect against this case by checking that the date list is not empty. I didn't add a test because I couldn't find a reproducing test case.
