    tests: Add additional keyfile assertions
    
    These slightly improve the tests but, more importantly, squash a
    scan-build warning about assigning to a variable which is never
    subsequently used:
    ```
    ../../../glib/tests/keyfile.c:1150:3: warning: Value stored to 'value' is never read
      value = g_key_file_get_string (keyfile, "a", "key=", &error);
      ^       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ../../../glib/tests/keyfile.c:1159:3: warning: Value stored to 'value' is never read
      value = g_key_file_get_string (keyfile, "a", "key[", &error);
      ^       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ../../../glib/tests/keyfile.c:1176:3: warning: Value stored to 'value' is never read
      value = g_key_file_get_string (keyfile, "a", " key", &error);
      ^       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    3 warnings generated.
    ```
