Need to check resources `fetchAll` for list/string inconsistencies

[flaneuse]

ugh. :(

getResourcesData(query = 'seroprevalence OR "sero-prevalence"', fetchAll = TRUE) -->

 Error: Can't combine `..1$license` <character> and `..2$license` <list>.

license is a list in some cases and string in others, triggering the error that the dataframes between pages can't be combined.
