Fix: FUL coming up when phone is powered off from lockscreen

When FUL was enabled and the power was turned off from the lockscreen,
either manually or by timing out, the lockscreen would turn back on
and FUL would start.

I believe this is due to a recently-added 'force' flag, which this
commit removes.
