`convert()`: `force_new=FALSE` being ignored

[bschilder]

Checked and the file it's being written to does indeed already exist:

x <-  "IMPACT707/Annotations/IMPACT707_EAS_chr1.annot.gz"
file.exists(echotabix::construct_tabix_path(target_path = x))
out <  echotabix::convert(target_path = x,
                           chrom_col = "CHR",
                           start_col = "BP",
                           comment_char = "CHR",
                           force_new = FALSE)

and yet file is still being reprocessed:
