rsample::group_vfold_cv -> splits . Factors converted to characters #167

Hello, I noticed that the newest version of rsample is transforming variables from factors to characters (within the splits at least), when applying group_vfold_cv.

In turn, if one is keen to use a formula (at least for the pls package): plsr(y~ -factor,...) the predict function outputs this error: Error incontrasts<-(tmp, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels

Can you provide a small, reproducible example?
