Fix predict net issue with LRU hash eviction
Summary:
We are seeing error "[enforce fail at BlackBoxPredictor.cpp:134] ! !parameter_workspace->HasBlob(out). Net REMOTE of type predict_net writes to blob cat/NGRAM_QRT_VERSIONS_x_EVENT_TYPE_AUTO_FIRST_X/Pool_Option_0/Repeat_0/sparse_lookup/w which exists in the parameter workspace" in online testing for calibration models.
I'm suspecting it's due to the op CopyRowsToTensorOp are being used in prediction
Test Plan:
f143080108 offline predict net does not contain CopyRowsToTensorNet, which looks right.
Waiting for Olga to test online behavior
