[R-pkg-team] Bug#961419: Bug#961419: r-cran-sjlabelled: autopkgtest failure

[Graham Inggs]

Control: affects -1 + src:r-cran-ggeffects
Control: affects -1 + src:r-cran-sjmisc
Control: affects -1 + src:r-cran-sjplot

I think this is also the cause of the autopkgtest failures in
r-cran-ggeffects [1], r-cran-sjmisc [2] and r-cran-sjplot [3].
