[BUG] No way to add a claimed device when no device exists yet

[floitsch]

When a user doesn't have any device the "claim device" button isn't visible.

Current work-around is to add a simulator first.

Go to Serial, connect the device and use the "Claim" button from there.

Agreed that it's a minor issue, but separate claiming is often when you don't have the device connected to the machine.
For example I had one user where the claiming initially failed because there was a brownout on the USB port.
As such, it's not really easy to connect the device since I had to move it away from the computer in the first place. Fwiw, it ended up being easier to just run toit device claim ... anyway, but still.
