Keep same extensions on different platforms

[jgonet]

Description

Fixes #1338.

Having different extensions (e.g. .ts and .tsx) caused Metro to prioritize one over another. This prevented .android.tsx from being loaded, as .ts was loaded first.

Test plan

Wrapped example app with gestureHandlerRootHOC in index.js and verified it on Android.

Tested on this code snippet:

import React, {Component} from 'react';
import {
  SafeAreaView,
  StyleSheet,
  StatusBar,
  ViewStyle,
  StyleProp,
  Animated,
} from 'react-native';
import {
  PanGestureHandler,
  PanGestureHandlerGestureEvent,
  PanGestureHandlerStateChangeEvent,
  State,
  TouchableOpacity,
} from 'react-native-gesture-handler';

type DraggableBoxProps = {
  minDist?: number;
  boxStyle?: StyleProp<ViewStyle>;
};
export class DraggableBox extends Component<DraggableBoxProps> {
  private translateX: Animated.Value;
  private translateY: Animated.Value;
  private lastOffset: {x: number; y: number};
  private onGestureEvent: (event: PanGestureHandlerGestureEvent) => void;
  constructor(props: DraggableBoxProps) {
    super(props);
    this.translateX = new Animated.Value(0);
    this.translateY = new Animated.Value(0);
    this.lastOffset = {x: 0, y: 0};
    this.onGestureEvent = Animated.event(
      [
        {
          nativeEvent: {
            translationX: this.translateX,
            translationY: this.translateY,
          },
        },
      ],
      {useNativeDriver: true},
    );
  }
  private onHandlerStateChange = (event: PanGestureHandlerStateChangeEvent) => {
    console.log('state');

    if (event.nativeEvent.oldState === State.ACTIVE) {
      this.lastOffset.x += event.nativeEvent.translationX;
      this.lastOffset.y += event.nativeEvent.translationY;
      this.translateX.setOffset(this.lastOffset.x);
      this.translateX.setValue(0);
      this.translateY.setOffset(this.lastOffset.y);
      this.translateY.setValue(0);
    }
  };
  render() {
    return (
      <PanGestureHandler
        {...this.props}
        onGestureEvent={this.onGestureEvent}
        onHandlerStateChange={this.onHandlerStateChange}
        minDist={this.props.minDist}>
        <Animated.View
          style={[
            styles.box,
            {
              transform: [
                {translateX: this.translateX},
                {translateY: this.translateY},
              ],
            },
            this.props.boxStyle,
          ]}
        />
      </PanGestureHandler>
    );
  }
}

const App = () => {
  return (
    <>
      <StatusBar barStyle="dark-content" />
      <SafeAreaView>
        <DraggableBox />
        <TouchableOpacity
          disabled={false}
          style={{width: 100, height: 50, backgroundColor: 'red'}}
          onPress={() => console.log('rngh')}
        />
      </SafeAreaView>
    </>
  );
};

const styles = StyleSheet.create({
  box: {
    width: 150,
    height: 150,
    alignSelf: 'center',
    backgroundColor: 'plum',
    margin: 10,
    zIndex: 200,
  },
});

export default App;
