Subject: [PATCH] Support npm5

npm5 installs modules and changes their `package.json`::`version` field to be something like
```
  "version": "https://registry.npmjs.org/rn-nodeify/-/rn-nodeify-7.0.1.tgz",
```
instead of
```
  "version": "7.0.1",
```

This commit adds support for that first type of string but also supports npm4.
