Adds 'phone' permission

[terhoraj]

Why does this automatically adds permission to access 'phone'?

Just faced the same problem when my app suddenly received a warning on Play Store, that READ_PHONE requires a privacy policy. The permission is added automatically by the build tools because this library doesn't have a minSdkVersion set. All libraries with a minSdkVersion older than 4 will have this permission added.

EDIT: this is not the only permission automatically added. Lack of minSdkVersion also brings to the party access to external storage read/write.
