This error sounds like you're trying to call #f as a function. Since
this is happening in the 'check-python-module phase, we can look at this
code:

>             (add-after 'install-python-module 'check-python-module
>               (lambda* (#:key inputs #:allow-other-keys #:rest args)

I assume that (assoc-ref py:%standard-phases 'check) is returning #f,
which is causing the error. Given you don't use inputs, you could try
the same thing as you've done for the other phases like:

    (add-after 'install-python-module 'check-python-module
      (assoc-ref py:%standard-phases 'check))

But I'm not sure that will help you if the assoc-ref is really returning
#f. I guess in the worst case you could just leave out the check phase
entirely.

Also, as an aside, I'm not sure where the 'prepare-python-module phase
is coming from. Does it actually exist?
