org-agenda: Fix bug when showing the new time

* org-agenda.el (org-agenda-show-new-time): Ignore invisible
text when inserting the new time as a text property.

* org-compat.el (org-move-to-column): New argument
`ignore-invisible' to turn on `buffer-invisibility-spec'.

Thanks to Marcin Borkowski and Karl Voit for reporting this.

org-capture: Fix bug when capturing with templates using `function'

* org-capture.el (org-capture): Store :return-to-wconf
earlier.
(org-capture-place-template): Don't store :return-to-wconf
when called from a capture template using `function', rely on
the early :return-to-wconf value store from `org-capture'.

Thanks to Brett Viren for raising this issue.
