Fix definiendum

[angerhang]

Patch for #99 when given

\begin{mhmodnl}[creators=jusche]{cakenumber}{de}
\begin{definition}
\definiendum[name=cakenumber,lemma=Koeffizient]{cakenumber} aus $R$ konstruiert
\end{definition}
\end{mhmodnl}

we have

 <omdoc:definition for="cakenumber?name=cakenumber, lemma=Koeffizient" xml:id="cakenumber.de.definition4" about="#cakenumber.de.definition4" stex:srcref="smglom/numbers/source/cakenumber.de.tex#textrange(from=2;1,to=4;16)">
