[0.15] - duplicate "tiles.lua" named "tiles - Copy.lua"

[Neemys]

With steam version

In "[factorio root]/data/base/prototypes/tile" folder there is a duplicate of "tiles.lua" named "tiles - Copy.lua".

I don't see eny reason for that file to be here as all entity inside it are already defined in tiles.lua.

Edit : There is also a "demo-trees - Copy.lua" in "data/base/prototypes/entity".
