Combined Silos do not remove keys correctly.

[Y1195]

When dispatching SiloUtil.None in a combined silo, it does not remove the value from the state.

Single Silo:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Silo = require(ReplicatedStorage.Packages.Silo)
local SiloUtil = require(ReplicatedStorage.Packages._Index["[email protected]"].silo.Util)

local initialState = {
	myValue = 123,
}

local mySilo = Silo.new(initialState, {
	Set = function(state, action)
		state.myValue = action.value
	end,
})

mySilo:Watch(function(state)
	return state
end, function(objects)
	print(objects)
end)

task.wait(1)

print("Set Empty")
mySilo:Dispatch(mySilo.Actions.Set({
	value = SiloUtil.None
}))

Final Output: {}

Combined Silo:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Silo = require(ReplicatedStorage.Packages.Silo)
local SiloUtil = require(ReplicatedStorage.Packages._Index["[email protected]"].silo.Util)

local initialState = {
	myValue = 123,
}

local mySilo = Silo.new(initialState, {
	Set = function(state, action)
		state.myValue = action.value
	end,
})

local MAIN = Silo.combine({
	mySilo = mySilo,
})

MAIN:Watch(function(state)
	return state.mySilo
end, function(objects)
	print(objects)
end)

task.wait(1)

print("Set Empty")
MAIN:Dispatch(mySilo.Actions.Set({
	value = SiloUtil.None
}))

Final Output: {myValue = 123}
Expected output: {}
