Test framework invocation panic

[cthulhu-rider]

following code does not work as expected

bc, committee := chain.NewSingle(t)
exec := neotest.NewExecutor(t, bc, committee, committee)

// contract := deploy()

inv := exec.NewInvoker(contract.Hash)

inv.Invoke(t, 0, "totalSupply")

Current Behavior

panic: runtime error: index out of range [0] with length 0 [recovered]
	panic: runtime error: index out of range [0] with length 0

fixed on my side by replacing NewInvoker() with CommitteeInvoker()
