    libtracker-common: improve test_path_evaluate_name environment handling
    
    Under some environments $PWD might not point where we expect, so simply
    use g_get_current_dir() instead.
    g_getenv() is documented to return a pointer that may get overwritten
    by subsequent calls to g_getenv, g_setenv of g_unsetenv. As even after
    removing the second g_getenv, there's still g_setenv calls, take a copy.
