[MC-88220] Applying the same attribute modifier to multiple slots only affects the last slot

When attempting to create an item that gives an attack bonus in either the main or off hand slot, only the second attribute is applied.

Steps to Reproduce:

Create an item with two identical attribute modifiers applied to mainhand and offhand, offhand second
Hold item in main hand and attack something - no boost
Hold item in off hand and attack something - boost is applied properly

Cannot confirm for 15w37a

Example command

/give @p iron_sword 1 0 {AttributeModifiers:[{Operation:0,UUIDLeast:0l,UUIDMost:0l,Amount:200d,AttributeName:"generic.attackDamage",Name:"sword",Slot:"mainhand"},{Operation:0,UUIDLeast:0l,UUIDMost:0l,Amount:200d,AttributeName:"generic.attackDamage",Name:"sword",Slot:"offhand"}]}
