Autocomplete onBlur handler isn't called as expected

## 🐛 Bug Report

## To Reproduce

Steps to reproduce the behavior:

1. Take the sample code for "Autocomplete Simple Usage" from https://akveo.github.io/react-native-ui-kitten/docs/components/autocomplete/overview#autocomplete

2. Add a simple `onBlur` handler like:

`onBlur={() => { alert('onBlur called!'); }}`

3. Use the Autocomplete component -> Enter some text then make it loose focus by touching/clicking on the background.

4. Notice that the `onBlur` handler is not called.

## Expected behavior

If supplied, `onBlur` should be called whenever the Autocomplete element loosed focus.

## Link to runnable example or repository (highly encouraged)

Can't seem to make a runnable Expo Snack currently, getting an odd error trying to load React.
