fix:3514: Avoid switching output country when Tor is running.

Description

I found a bug in current main branch:

1. Activate IpScrambling
2. Go to Manage Ipscrambling screen, and change out put country
3. Then the Device can't resolve DNS, and any web request fail.

I didn't find root cause of this bug. Most likely it is related to the recent update of Orbot (but I'm surprised to observed it just now, I did another fix arount the select country feature at that occasion...). As a quick workaround, I blocked the change of exit country while Tor is ON, and add a little tooltip to inform the user about it.

@aude is it ok for you ?
