But also keep the old name as (undocumented) compatibility around. The reload-or-try-restart was documented to be a NOP if the unit is not running, since the previous commits this is also implemented. The old name suggests that the "try" logic only applies to restarting. Fix this, by moving the "try-" to the front, to indicate that the whole option is a NOP if the service isn't running.
