feat(derived parameters): gracefully catch errors when deriving parameters inside tests

The propeller size function has not inverse, hence we canot infer
the propeller size specification from the FC parameter values.
The test file tests/acceptance_template_import_from_params.py assumes
size 0, and that causes parameter derivation to fail.
This code catches that.
