in D23858329 (https://github.com/pytorch/pytorch/commit/721cfbf8425cf2c1dc5e27d1332e32e1a42ef541), we put PriorCorrectionCalibrationPrediction unit test in OSS file which causes test failure issue in public trunk.
this diff moves it to FB only test file.
Test Plan:
```
buck test //caffe2/caffe2/python/operator_test:torch_integration_test -- test_gather_ranges_to_dense_op
buck test //caffe2/caffe2/fb/python/operator_test:torch_integration_test -- test_prior_correct_calibration_prediction_op
```
all pass.
