Error returns on install any plugin from GitHub. For example:
```
ionic cordova plugin add https://github.com/appodeal/appodeal-cordova-plugin.git
ionic cordova plugin add https://github.com/appodeal/appodeal-cordova-plugin.git
```

But executing `cordova plugin add ...` without `ionic` works fine

**Steps to Reproduce:**

1. Create new project
2. Try to install plugin with `ionic cordova plugin add ...`

**Output:**
