[Ovmsdev] Wrong Roadster Data

Opening the door didn't help.

I was wondering if I was getting data from another Roadster, so I checked
the Location view. It's showing the spot where the car was parked yesterday
afternoon, and in fact all of the data is consistent with that: SOC and
locked status. Since then, the car has been driven twice and charged, so
plenty of opportunity to get current CAN bus readings.

The other odd thing is that it shows it's been parked for 5 minutes every
time I update it.

The only thing unusual yesterday was that I realized I hadn't locked the car
a couple of minutes after we parked, so I used OVMS to lock the car, and
checked the Car view to confirm it was locked.

Could that have frozen things for some reason?

I'll try rebooting the car module before I drive it this morning.
