Tails Installer should autodetect if Tails is installed on the destination device
To simplify the workflow regarding install or upgrade (and as long as Tails Installer does the upgrades, see #7499) we propose the following:
- Tails Installer start from its main interface straight away (see #8859 (closed)).
- When the destination device has Tails installed already, the “Install” button is rename “Reinstall” (or something similar) and an “Upgrade” button appears below it.
