fix(modeline): remove advice causing org-element cache errors in org

This advice was suppressing ws-butler's modification hooks, which had a
nasty side-effect of modifying org buffers without letting its
org-element cache know that it's stale, which resulted in errors like
this, followed by a backtrace:

  Warning (org-element): org-element--cache: Unregistered buffer modifications detected (175 != 176). Resetting.
  If this warning appears regularly, please report the warning text to Org mode mailing list (M-x org-submit-bug-report).

The advice isn't needed anymore, anyhow.
