tests: Fix a -Wmaybe-uninitialized warning
Since the `switch` didn’t have a default case, the `cull_front` and `cull_back` variables could technically be used uninitialised if the `cull_mode` was unrecognised. That seems unlikely to happen as presumably other code makes sure the `cull_mode` is valid, but it doesn’t hurt to add a `default:` case to squash the compiler warning.
