In case of errors, make sure that no retrievals are marked "in progress"

* gnus-start.el (gnus-get-unread-articles): Clear out "early" methods
so that previous errors don't prohibit getting new news.

* nnimap.el (nnimap-retrieve-group-data-early): Ditto.

* nntp.el (nntp-retrieve-group-data-early): Ditto.
