[libgweather/location-object] tests: Turn random output into test messages

[Emmanuele Bassi <ebassi src gnome org>]

commit c1ace687caad97d32b213687ab2595eada05e84f

    tests: Turn random output into test messages
    
    The g_test_message() function ensures that the output does not break any
    TAP harness. Replacing the random g_print/g_debug/g_message with
    g_test_message() has the additional benefit of not requiring a custom
    log handler.
