Fix CI: typo lfqdata$conf -> lfqdata$config and quote bare contrast in unnest

- LFQDataImp.R: lfqdata$conf was NULL (correct field is config), causing
  example crash on CI where zCompositions is installed
- logistf.R, tidyMS_R6_Modelling.R: quote "contrast" in unnest(cols=)
  to fix R CMD check NOTE about undefined global variable
