autocor fails

[jmorten]

Example from ?cor_bsts:

dat <- data.frame(y = rnorm(100), x = rnorm(100))
fit <- brm(y~x, data = dat, autocor = cor_bsts())

Error in if (nzchar(bterms$time$group)) { : argument is of length zero
In addition: Warning messages:
1: There were 4 chains where the estimated Bayesian Fraction of Missing Information was low. See
http://mc-stan.org/misc/warnings.html#bfmi-low 
2: Examine the pairs() plot to diagnose sampling problems

Thanks! It should be fixed now in the dev version of brms.
