unzip error when using glove embeddings from torchtext

[lasgel]

🐛 Bug

Describe the bug A clear and concise description of what the bug is. When using GloVe from torchtext.vocab an error occurs saying that

zipfile.BadZipFile: File is not a zip file

To Reproduce Steps to reproduce the behavior:

1. Go to a directory where torchtext has not been used (meaning that there is no .vector_cache)
2. from torchtext.vocab import GloVe
3. glove = GloVe(name='6B', dim=50) or use any other valid combination of name and dim
4. See error

Expected behavior The server at Stanford university from where it is downloaded is down till 3rd of July, so instead of trying to unzip a zip file where just a 404-page is stored (and is no zip archive either) one would expect to get a message that the download could not be completed

Environment torchtext Please copy and paste the output from our environment collection script (or fill out the checklist below manually).
