tests are busted again

[crew102]

some are getting skipped b/c of issues with underscores in figure names, some are failing b/c of issue with unloading packages here:

ggExtra/tests/testthat/helper-funs.R

Lines 144 to 146 in 62299ff

	unloadPackages(
	c("vdiffr", "purrr", "ggplot2", "tibble", "testthat", "pillar", "rlang")
	)

Fun! 🎉
