There's a "kekatar" error when uncompressing files compressed with Keka, if "Exclude Mac resource forks" was unchecked

To replicate the bug (it seems to happen every time), do this:

Make sure that "Exclude Mac resource forks" isn't checked, then try to compress the Keka.app (not just any random file... put the Keka.app from the DMG somewhere... in the Downloads folder or wherever you want... and try compressing it) with Keka, using BZIP2, XZ or GZIP... then try to uncompress it with Keka... it uncompresses, but it shows an error:

> Error code 1 using "kekatar"
> Unknown error

This happened with v1.1.20 and it still happens with v1.1.21

I tried to just compress some random PDF using "ditto --hfsCompression" and then to compress it and uncompress it with Keka, to see is using HFS+ compression maybe causing an issue for Keka, but it didn't show an error
