prioritize() with 0-row df fails ungracefully

[maurolepore]

match_name() can return a 0-row data frame. I expected prioritize() to handle such input more gracefully.

library(r2dii.data)
library(r2dii.match)

matched <- match_name(head(loanbook_demo), head(ald_demo))
#> Warning: Found no match.
identical(nrow(matched), 0L)
#> [1] TRUE

# Fails ungracefully
try(prioritize(matched))
#> Error in select_chr(sort(unique(data$level)), tidyselect::matches("direct"),  : 
#>   is.character(x) is not TRUE
