Fixed build issues on Android using API 19

I was receiving these errors when using this plugin for Android API 19:
```
     [aapt] /Users/sashasirotkin/Projects/REDACTED/platforms/android/ant-build/AndroidManifest.xml:19: Tag <uses-permission> missing required attribute name.
     [aapt] /Users/sashasirotkin/Projects/REDACTED/platforms/android/ant-build/AndroidManifest.xml:20: Tag <uses-permission> missing required attribute name.
     [aapt] /Users/sashasirotkin/Projects/REDACTED/platforms/android/ant-build/AndroidManifest.xml:21: Tag <uses-permission> missing required attribute name.
