Correct timing when attaching lit candles to the candelabrum

Browse Source 
Before this commit, attaching a lit candle would reduce the amount
of fuel in the candelabrum to 0, 15 or 75 turns due to a failure to
account for time stored in the candle's burn timer. Fixing this is
very important because a time of 0 turns on the candelabrum is not
supposed to be possible.
