[Workflow notifications] Minor thought... shouldn't it also reset the last_email_run state when the "Enable email notifications" box has become ticked? Else the user would receive a flood of old notifications as soon as they [re-]enable e-mails!

          Minor thought... shouldn't it also reset the `last_email_run` state when the "Enable email notifications" box has become ticked? Else the user would receive a flood of old notifications as soon as they [re-]enable e-mails!

Or perhaps simpler, for the same effect, just update state every time within hook_cron during the early-return?
