deal with warnings in tests

[hfrick]

I'm seeing a lot of warnings in the tests of the type below, would be nice to clean up 🧹

Warning (test-mars.R:72:3): check model reduction
non-uniform 'Rounding' sampler used
Backtrace:
  1. baguette::bagger(...)
       at test-mars.R:72:2
 24. dplyr `<fn>`(`<smplWrnn>`)
 25. dplyr:::check_muffled_warning(w)
 26. base::withRestarts(...)
 27. base withOneRestart(expr, restarts[[1L]])
 28. base doWithOneRestart(return(expr), restart)

We also see quite a lot of warnings about the now-deprecated fit_control():

Warning (test-validation.R:153:3): model failures inputs
`fit_control()` was deprecated in parsnip 0.1.8.
Please use `control_parsnip()` instead.

These do not appear to surface any more. The round issue has gone away since R versions in our range of supported releases have consistent RNG settings
