Upgrading mapomatic breaks DD tests

[kevinsung]

The mapomatic commit that broke the code was introduced between mapomatic versions 0.9 and 0.10: qiskit-community/mapomatic@208989e

This prevents us from upgrading mapomatic past 0.9, which in turn blocks us from upgrading to Qiskit 1.0, because mapomatic 0.9 depends on qiskit-terra.

Example test failure (see CI logs of #107 for full test failures):
