Revert changes to exception message (#803)

* Revert changes to exception message We used to log "No RCF models are available either because RCF models are not ready..." and now we log "resource_not_found_exception: No checkpoints found for model id...". This change caused an integration test failure. This PR reverts it back. Testing done: 1. verified that the original log is back. Signed-off-by: Kaituo Li <[email protected]> * check NO_MODEL_ERR_MSG instead of NO_CHECKPOINT_ERR_MSG Signed-off-by: Kaituo Li <[email protected]> --------- Signed-off-by: Kaituo Li <[email protected]> (cherry picked from commit 553688a)
