Fuel consumed is not zeroed when there is no fire happened

Line 376 in a19c26d

currentPatch%TFC_ROS = sum(fuel_consumed) - fuel_consumed(fuel_classes%trunks())

This TFC_ROS variable is used for determining fire intensity. Claculated fire intensity is then used to determin if a fire occurs or not. But under a no fire situation, TFC_ROS is never zeroed. History variable FATES_FUELCONSUMED refers to this variable, thus is wrong given its value never gonna be zero unless there is no fuel or fuel is too wet.

@XiulinGao thanks for finding this! not sure if this is new as of my refactor or it was always there? strange that we didn't catch it in regression testing if it was mine

@adrifoster it was there since the beginning. I have noticed this for several fire-related variables before, but most is already corrected by your refactor.
