Redstone wire name displayed in the inventory, doesn't match with the ID in Command Block

In the inventory, the name displayed of the Redstone wire doesn't match with the ID which use the Command Blocks

In the inventory, the name is "minecraft:redstone", but, if we put this name in a Command Block, this will produce an error : "There is no such item with the name minecraft:redstone".

Actually, if we put "minecraft:redstone" in a Command Block, this produce an error.
The error is ""There is no such item with the name minecraft:redstone".

Steps to Reproduce:

1. Put this in a Command block "/setblock ~1 ~0 ~0 minecraft:redstone 0 replace"
2. An error message will be displayed.
3. Change the name in "minecraft:redstone_wire", the wire will be placed.
