Fix ordering of ParseCommandLineFlags() & InitGoogleTest() for Windows.

- On Windows gtest passes additional non-gflags command line flags
  for death-tests, to avoid gflags invoking an error for these flags
  InitGoogleTest() must be called before ParseCommandLineFlags() to
  handle and remove them before gflags parses the remaining flags.
