fix: correct try/except statement

[marsam]

Otherwise, it fails because Python can't find the jq exception.

==================================== ERRORS ====================================
______________________ ERROR collecting tests/test_jq.py _______________________
tests/test_jq.py:8: in <module>
    import jq
E   ModuleNotFoundError: No module named 'jq'

During handling of the above exception, another exception occurred:
tests/test_jq.py:9: in <module>
    except jq:
E   NameError: name 'jq' is not defined
