bug: state.ChainID() returns empty string

[altergui]

this should happen during init

vocdoni-node/vochain/app.go

Lines 557 to 563 in 8709a6f

	}
	// SetChainID sets the app and state chainID
	func (app *BaseApplication) SetChainID(chainID string) {
	app.chainID = chainID
	app.State.SetChainID(chainID)
	}

but only vocone calls app.SetChainID() during init,
vocdoni-node doesn't, it simply sets

vocdoni-node/vochain/start.go

Line 263 in 3c074b3

app.chainID = genesisCID.ChainID

since almost noone uses state.ChainID(), this has almost no consecuences... except one, crucial:

vocdoni-node/vochain/processid/process_id.go

Lines 184 to 186 in 3fb5c2c

	func BuildProcessID(proc *models.Process, state *state.State) (*ProcessID, error) {
	pid := new(ProcessID)
	pid.SetChainID(state.ChainID())
