Steps to reproduce the issue

restore an article from the versions model.

Expected result

1. The "Saved on" date show from $model->getState('save_date') to respect my language file date format (any of them, Im not picky ;-))

DATE_FORMAT_CALENDAR_DATE="%m-%d-%Y"
DATE_FORMAT_CALENDAR_DATETIME="%m-%d-%Y %H:%M:%S"
DATE_FORMAT_FILTER_DATE="m-d-Y"
DATE_FORMAT_FILTER_DATETIME="m-d-Y H:i:s"
DATE_FORMAT_JS1="m-d-y"
DATE_FORMAT_LC="l, F d, Y"
DATE_FORMAT_LC1="l, F d, Y"
DATE_FORMAT_LC2="l, F d, Y H:i"
DATE_FORMAT_LC3="F d, Y"
DATE_FORMAT_LC4="m-d-Y"
DATE_FORMAT_LC5="m-d-Y H:i"
DATE_FORMAT_LC6="m-d-Y H:i:s"

2. if there was no $model->getState('version_note') to show something like (No Version Note) instead of a space that then pushes the period looking odd.

Actual result

caused by language string:

JLIB_APPLICATION_SUCCESS_LOAD_HISTORY="Prior version restored. Saved on %s %s."

$this->setMessage(
Text::sprintf(
  JLIB_APPLICATION_SUCCESS_LOAD_HISTORY', $model->getState('save_date'), $model->getState('version_note')
  )
);

System information (as much as possible)
