Fix test with the Setup Setting Test

[cpapplefamily]

This bit of code causes the test to fail but I am getting the desired functions

Particulary the "numAlliances, _ = strconv.Atoi(r.PostFormValue("numPlayoffAlliances"))" in the else section

var playoffType model.PlayoffType
	numAlliances := 0
	if r.PostFormValue("playoffType") == "SingleEliminationPlayoff" {
		playoffType = model.SingleEliminationPlayoff
		numAlliances, _ = strconv.Atoi(r.PostFormValue("numPlayoffAlliances"))
		if numAlliances < 2 || numAlliances > 16 {
			web.renderSettings(w, r, "Number of alliances must be between 2 and 16.")
			return
		}
	} else {
		playoffType = model.DoubleEliminationPlayoff
		numAlliances = 8
		log.Printf("setup_settings.go playoffType: %v", playoffType)
		log.Printf("setup_settings.go eventSettings.ElimType: double")
		numAlliances, _ = strconv.Atoi(r.PostFormValue("numPlayoffAlliances"))
		log.Printf("setup_settings.go numAlliances: %v", numAlliances)
		
		if  numAlliances < 3 || numAlliances > 8 {
			web.renderSettings(w, r, "Number of alliances For Double Must be between 3 and 8.")
			return
		}
	}
