An ML type error in Apply_Trace.thy with Isabelle2017

[pirapira]

On the branch issabelle2017, when I run

<somewhere where Isabelle2017 was extracted>/Isabelle2017/bin/isabelle build -d . simplewallet

I see

*** Failed to load theory "simplewallet.Apply_Trace_Cmd" (unresolved "simplewallet.Apply_Trace")

@seed told me a workaround: replacing apply_trace with apply.
