R4R: Simulator: Set Quorum field in appStateRandomizedFn

[smoelius]

This avoids a nil pointer dereference, e.g., when the simulator displays log messages. This change
is intended to be consistent with:

cosmos-sdk/x/gov/genesis.go

Lines 60 to 63 in 5d05b7f

	TallyParams: TallyParams{
	Quorum: sdk.NewDecWithPrec(334, 3),
	Threshold: sdk.NewDecWithPrec(5, 1),
	Veto: sdk.NewDecWithPrec(334, 3),
