feat(log-state): align with the emacs orgmode format

[milanglacier]

In emacs orgmode, the org-log-note-headings is defined as follows:

(defcustom org-log-note-headings
  '((done .  "CLOSING NOTE %t")
    (state . "State %-12s from %-12S %t")
    (note .  "Note taken on %t")
    (reschedule .  "Rescheduled from %S on %t")
    (delschedule .  "Not scheduled, was %S on %t")
    (redeadline .  "New deadline from %S on %t")
    (deldeadline .  "Removed deadline, was %S on %t")
    (refile . "Refiled on %t")
    (clock-out . ""))
  "Headings for notes added to entries.

This commit changes the log state format so that it is aligned with emacs orgmode.
