[2.1.14] Personal construction bots repeatedly attempt and fail to build "neutral" force ghosts

[Shemp]

To reproduce:

• Enter a standard Factorio world, just the base mod is enough.
• Equip Power armor and a Personal roboport, a power source for the armor, and place Construction bots in your inventory.
• Give your character a bunch of Assembling machine 1s.
• Run the following command to spawn a ghost on the "neutral" force:
• /c game.surfaces.nauvis.create_entity{name = "entity-ghost", inner_name = "assembling-machine-1", position = game.player.position, force = "neutral"}
• Your Construction bots will repeatedly attempt to build the ghost when it is in range, but the bots will never place the items.

I expect the ghost to be visible to the player, because LuaForce::is_friend is always true for the "neutral" force, but robots should not attempt to build it, following the behaviour for other friendly forces.

This bug does not affect static Roboport buildings.

Thanks for the report. This is now fixed for the next release.
