getThemeInfo()$dark can be NA

[nicknimchuk]

I haven't been able to reproduce this myself, but per this post in the RStudio Community:
https://community.rstudio.com/t/library-tidyverse-results-in-error-on-r-studio/2642/13

A call to getThemeInfo() can return:

$editor
NULL

$global
[1] "Modern"

$dark
[1] NA

This results in an error in text_col:

Error: package or namespace load failed for ‘tidyverse’:
 .onAttach failed in attachNamespace() for 'tidyverse', details:
  call: if (theme$dark) crayon::white(x) else crayon::black(x)
  error: missing value where TRUE/FALSE needed

This is clearly a problem with the IDE or the API (and I've filed an issue with the API as a first step), but seems worth putting a band-aid on it for those that will update tidyverse more than the IDE.
