Description

For a unit test, I am creating a dummy data set with only four points. I can create a 10-fold cross-validation task for it without receiving an error. However, the splits file is broken; it contains a wild mixture of separators, xml, json, and html, including the following error message:

{"error":"Can't have more folds than instances!"}

Makes sense :)
This is easy enough to check and should therefore be reported at task creation time.
