[Orgmode] Bug in column view with cookie on item line

[Indraneel Majumdar]

 With [%] or [/] set to update, the item line gets mangled as soon as 
TODO is changed to DONE from column view.

Here's what it looks like:

** TODO test 1 [/]
:PROPERTIES:
:Effort: 1
:END:

*** T[0/1[0/1[0/1[0/1[0/1[1/1]] <<< MANGLED AGAIN (line was TODO test 1 [/])
:PROPERTIES:
:Effort: 1
:END:

**** DONE [0/1[0/1[0/1[0/1[0/1[1/1]/] <<<<<<<<<<<<<<<< MANGLED
