sst_dump --command=recompress --compression_types=kNoCompression does uncompress nothing in the case of that specific file

I have a file compressed using Snappy but when I try to use `sst_dump` from the latest commit, the file is left unchanged.

sh-5.1# ./sst_dump --file=/mnt/xdai/db/3c648cbdc4c9333d/archive/db/1864667.sst --command=recompress --compression_types=kNoCompression
from [] to []
