download_packages() returns double-slashed path ("//home/hb/.cache/...")

[HenrikBengtsson]

Just an FYI: No error per se, but I noticed the following double-slash path that looks like a mistake:

> res <- crancache::download_packages("R.utils", destdir = tempdir())
> res
     [,1]     
[1,] "R.utils"
     [,2]                                                                
[1,] "//home/hb/.cache/R-crancache/cran/src/contrib/R.utils_2.8.0.tar.gz"
> dir(tempdir())
[1] "downloaded_packages"
