[0.17.62] Tutorial: Electric furnace refuses to smelt iron plates

[mward]

The electric furnaces in the North West corner of the map refuse to smelt iron plates.
They say "Iron plate cannot be smelted": which is false. Stone and steel furnaces will smelt iron plates to steel. Also: the inserters will not pick up iron plates from the belt.

The furnaces will smelt iron ore, copper ore and stone.

Indeed.

Issue looks to be that they belong to force "bystrander" that has not yet researched "Steel"

This has already been fixed as part of the fix for 73335.
They should all be on the player force in current experimental (0.17.63)
