ClipboardStore: Rename "last", only set it on first run

* Rename `last` to `original` because we only want to set it the first
  time we set the clipboard. Subsequent times we set the clipboard
  contents should not affect this saved value.
* Only set `original` on first run of the clipboard `set_contents`
  function.
