Facets argument of facet_grid() deprecated

[joannalingzj]

Hi,
I was running mcmc_acf and got this warning message.
mcmc_acf(posterior_b5, pars = c("b_Intercept","b_time","sd_Batch__Intercept","sd_Batch__time","sigma"), lags = 20)
Warning message:
The facets argument of facet_grid() is deprecated as of ggplot2 2.2.0.
ℹ Please use the rows argument instead.
ℹ The deprecated feature was likely used in the bayesplot package.
Please report the issue at https://github.com/stan-dev/bayesplot/issues/.
This warning is displayed once every 8 hours.

Thanks for reporting this!

Coming back to this, I think this was actually fixed in #305. So it shouldn't produce a warning in the latest version of bayesplot. If it still does we can reopen this and look into it.
