Thunderbird doesn't start if ~/.icedove exists and is empty

Originally created by @goupille on #12734 (Redmine)

as a workaround, set up an administrator password in the greeter, then after Tails has started, open a terminal and type

sudo sed -i '/icedove/d' /live/persistence/TailsData_unlocked/persistence.conf

and enter.
