bug#65304: refresh can't update profanity

[Jack Hill]

I'm using ./pre-inst-env guix from commit 
19a7a824c35eae56ce56e2a460042fb7e2129234. `guix refresh -u profanity` 
doesn't seem to be able to find the new tarball for download. However, if 
I do the update by hand, `guix build` knows how to download the tarball. 
The profanity source record looks like this:

"""
 (source
     (origin
       (method url-fetch)
       (uri
        (string-append 
"https://profanity-im.github.io/tarballs/profanity-";
                       version ".tar.gz"))
       (sha256
        (base32
         "14n45zwc6fxjargqhwqan8fyb7x0ql0hmw56rbjkjfkhpba2qmks"))))
""""

Here's refresh getting confused:

"""
