mbed-host-tests tests fail with Python 3.12

[knowledgejunkie]

Description

The mbed-host-tests package fails to build on Debian sid with Python 3.12, due to failing tests.

The failures are due to the stricter assertion checks in 3.12, which forbid assertions starting with "called_once..."

Relevant part (hopefully):
