Issue description

Current behavior:

Spinner fails to render with:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: %s.%s%s, undefined, You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Expected behavior:
The Spinner would render.

Steps to reproduce:
I'm just adding the spinner to the code and it doesn't work. Removing the spinner makes the component render

Related code:

import { Text, List, withStyles, Spinner } from 'react-native-ui-kitten'
//...
function Stations({stations, loading, error, themedStyle}) {
    return (
      <SafeAreaView>
        <View style={{...themedStyle.container, ...themedStyle.containerBlankState }}>
          <Spinner />
          <Text category="h4">Carregando os dados das suas estações</Text>
        </View>
      </SafeAreaView>
    )
}

Hi! Please upgrade UI Kitten to beta, since it’s not available in this version

npm i react-native-ui-kitten@beta
