org-agenda.el: Fix bug when redoing sticky agendas with log mode and/or clockreport mode on

* org-agenda.el (org-agenda-mode): Let `org-agenda-redo' DTRT
when agenda are sticky.
(org-agenda-tag-filter-while-redo): Delete.
(org-agenda-list, org-agenda-redo, org-agenda-filter-by-tag):
Remove unused code.
(org-agenda-clockreport-mode, org-agenda-set-mode-name): Don't
consider tag filters.

Thanks to Bernt Hansen for reporting this.
