attempt to index a nil value (g lobal 'l3kernel')

[pddzaic]

The following MWE leads (second run with lualatex) to an error:

\documentclass{article}

\usepackage{acro}

\DeclareAcronym{A}{
  short      = {AAA},
  long       = {Die Abkürzung AAA}
}

\DeclareAcronym{B}{
  short      = {BBB},
  long       = {Die Abkürzung BBB}
}

\begin{document}

\printacronyms

Hier: \ac{A}

Hier: \ac{B}

\end{document}

The error is:

(C:/PortableApps/Miktex/texmfs/install/tex/latex/translations/dicts/translation
s-basic-dictionary-english.trsl)[\directlua]:1: attempt to index a nil value (g
lobal 'l3kernel')

Thanks for this. It has to do with sorting and has to do with the reason for PR #231.
It is already fixed in acro. I'll make a release soon.
