fail gracefully if code object can't be extracted from fixture

[kapilt]

i was trying out pytest-opentelemetry, seems pretty cool, but ran into one issue due to some dynamic fixtures from pytest-terraform, which allows for fixture parameterization via class creation on the decorator, this unfortunately causes a traceback for pytest-opentelemetry. can this be changed to fail gracefully via conditional and getattr(). happy to put up a pr, if open to that.

     
fixturedef.execute(request=subrequest)

in this case the fixture is actually a callable class instance, which is why the func code object lookup fails.
