org-agenda: Write only currently visible items
* lisp/org-agenda.el (org-agenda-write): Fix arguments passed to
`org-agenda-remove-marked-text' to properly remove entries with
`invisible' property set to `org-filtered'.
* lisp/ox-icalendar.el (org-icalendar-export-current-agenda): Always
include TODO entries in the output. The motivation is that a user not
filtering out TODO or DONE items in the current agenda probably wants
them in the output.
