Fake model already exists error

[mytang0]

When executing the download command (sh models/download-ggml-model.sh base.en), the download failed due to SSL.
But there will also be an empty file called ggml-base.en.bin. When the download command is executed again, it will be displayed that the model already exists.

Downloading ggml model base.en from 'https://huggingface.co/ggerganov/whisper.cpp' ...
Model` base.en already exists. Skipping download.
