Timer undo function does not work on finished timer on startup

[zoton2]

How to replicate:

• Get the timer into a finished state
• Stop/start NodeCG
• Attempt to undo the timer

You will notice it appears to go into the running state, but the timer goes back to 0 and does not move.

I was able to fix this so it goes back to the same time that the timer was at when it was finished. If I was to store more information about the timer, for example made the timestamp update all the time, I could probably make it so you the time could actually be recovered.
