Tails installer proposes to install in laptop's eMMC internal storage

Reported by user, I cannot try for lack of hardware:

Apparently, when trying to install with Tails Installer, if your laptop has eMMC internal storage like HP Stream, it appears as the default option to install Tails onto.

Maybe worth to confirm and fix, or at least put a warning message somewhere in the docs.
