org-clock.el (org-clock-in): Don't forward by one character when setting the marker in the clock history

* org-clock.el (org-clock-in): Don't forward by one character
when setting the marker in the clock history.

This was done to prevent the marker from being broken when a user
manually insert some text right one it.  I cannot reproduce this
manual marker modification problem, so let's remove this ugly
exception, as it is not consistent with other clock markers.

Thanks to Bernt Hansen for pointing this out.
