[2.0.73] LuaControl::mine_entity flying text appears at odd position

[thesixthroc]

Corner case: If you call `player.mine_entity` on an entity at {x, y} on a different surface to the player, flying text is created on the player's surface.

This wouldn't be a problem, but the flying text appears at {x, y} on the player's surface, which is confusing because this physical spot is unrelated to either the player or the entity. It should probably be created at the player's position.

Thanks for the report. This is now fixed for 2.1.
