Case 2 in the help example for download.datasets() is broken again

[sfweller]

If you run the following, you will get an error:

name <- "Blood donation data"
ws <- workspace()
frame2 <- download.datasets(datasets(ws), name)

Error:

frame2 <- download.datasets(eval(parse(text=go)), name)
Error in as.data.frame.default(datasets) : 
 cannot coerce class ""function"" to a data.frame

No longer replicable.

Most likely fixed during refactoring of #111
