sienaGOF with join=FALSE is incorrect

[TomSnijders]

Description
Running sienaGOF for 3 or more waves with join=FALSE and a fixed&tested effect gives an error when calling the summary method.

To Reproduce
mynet <- sienaDependent(array(c(s501, s502, s503), dim=c(50, 50, 3)))
mydata <- sienaDataCreate(mynet)
myeff <- getEffects(mydata)
myeff <- setEffect(myeff, cycle3, fix=TRUE, test=TRUE)
myalgorithm <- sienaAlgorithmCreate(nsub=1, n3=10, projname=NULL)
ans <- siena07(myalgorithm, data=mydata, effects=myeff, batch=TRUE, returnDeps=TRUE)
gofi <- sienaGOF(ans, IndegreeDistribution, verbose=TRUE, varName="mynet", join=FALSE)
summary(gofi)
