Subject: [PATCH] Download latest stable Supervisor after device wipe (#2765)

* Download latest stable Supervisor after device wipe

Currently we download the latest tag after a device wipe, which gives us
the latest Supervisor (which quite likely can be a development version).
Use the stable version file instead to get the tag to be used to
download the Supervisor.

* Delete potentially corrupted updater info
