    Fixed the test threads/spawn/th_taskmaster · b6b638af

    According to the standard, collectives using the same communicator must
    implement thread safety in the application level. So, if using
    MPI_Comm_spawn in THREAD_MULTIPLE safety level, it must use different
    communicators.
    
    I've modified the test to use different communicators per thread so that
    we can still test its thread safety.
    
    Fixes #2256
