Fix recursive implementation of From<Number> for f64 (#2695)

The current code, I assume, attempted to hand over such implementation to that of `From<&Number> for f64`, but not only did it use the ambiguous `.` dot method syntax, it also forgot to take a reference to `n`, resulting `<Number as Into<f64>>::into` being called, whose implementation comes from the blanket `From -> Into` impl, effectively resulting in a recursive definition.
