fix(todo): no fix sooner than the wait asked for (ADR 0033, D32)

A LocationRequest allows fixes six times as often as asked unless it
says otherwise, so on the fused provider they came every 15 s where
30 s was asked: too soon to count towards lying still, and the wait
never grew. On the emulator it now goes 30, 60, 120, 240 s.
