Add Namespace to android build.gradle

[GeorgeChernyshov]

Please add namespace "com.stripe.reactnative" or something like that in your build.gradle. Without it, it is impossible to build the library on newer Gradle versions. Afaik newer React-native versions also require that.

This will also require removing package name from AndroidManifest.xml
