bake and juice shuffle columns around

[EmilHvitfeldt]

Minor quality of life issue. The response variable is moved to the end of the data.frame when juice() is called, but stays in its place when bake() is called.

An update to xgboost package makes this even more annoying. While using a recipe in caret and xgboost as a model, xgboost fails to do any prediction due to having the order of the columns in data and newdata different.

[EmilHvitfeldt]

This appears to have been solved by #397 so I'm gonna close this issue
