Discord Webhook Duty Clock does not correctly handle job switching.

This is a bug that's been a bit of a headache for me personally.

Right how there seems to be an issue with how the duty clock discord webhook handles someone switching job.

So if someone switches job and does not clock out of their current job before hand there will only be a clock in message for the business you are clocking into and not a clock out message for the one you are clocking out of.

There is also an issue where clock out messages are not posted if you stay clocked in during a server shutdown.

Should be an easy fix and i would love to see it sooner than later since a lot of businesses are facing this problem now.

Pretty much what needs to happen:

- Send a clock out when you switch job

- Before server shutdown clock out all currently clocked in players

- On server start-up also clock out all currently clocked in players (For crashes etc)

This should make it reliable enough that my fancy data tracking works without having to worry about things! Thanks a bunch!
