    tests: make warnings non fatal for tests on win32.
    
    g_test_init() makes any warning message fatale by default. While it
    makes sense for the main OS that we build on (Linux), I believe that
    our tests on Windows are more useful when they finish, even with some
    warnings, than stopping because some stupid font warning would occur
    (case I encountered, did not know the solution of, and is not really
    relevant to the rest of the test).
