Adrien Ball 88909a9adb Fix egg fragments in direct download (#3369)
## Description
The egg fragment in the URL must be of the form `#egg=package_name==version` instead of `#egg=package_name-version`.
One of the consequences of specifying wrong egg fragments is that `pip` does not recognize the package and its version properly, and thus it re-downloads the package systematically.

I'm not sure how this should be tested properly. 
Here is what I had before the fix when running the same direct download twice:
```
$ python -m spacy download en_core_web_sm-2.0.0 --direct

```

### Types of change
This is an enhancement as it avoids unnecessary downloads of (potentially big) spacy models, when they have already been downloaded.
