Set "replaceEnabled" to false, alert won't show up

[wellyshen]

Issue Description

Thank you for this great library. When I set the replaceEnabled to false. The alert component won't show up. But it works fine when the replaceEnabled set to true.

Steps to Reproduce / Code Snippets

import React from 'react';
import type { Element } from 'react';
import DropdownAlert from 'react-native-dropdownalert';

import styles from './Toast.styles';

type Props = { setRef: (ref: any) => void };

export default ({ setRef }: Props): Element<any> => (
  <DropdownAlert
    containerStyle={styles.container}
    messageStyle={styles.message}
    closeInterval={3500}
    updateStatusBar={false}
    replaceEnabled={false}  // <== The alert will show up when it set to "true"
    ref={ref => setRef(ref)}
  />
);

Expected Results

Alert show up and animation won't dismiss while message changed.

It looks like the animation routine is not invoked when false. I'll fix it up.

      if (this.state.isOpen == false) {
        this.animate(1);
      }

Hi @testshallpass Any update for this issue?

[testshallpass]

Sorry for the delay. I must have initially interpreted the issue wrong. I am not able to reproduce it.

@testshallpass

Here's my steps:

1. Set replaceEnabled={false} at beginning
2. Use method alertWithType() to display toast
3. Toast won't be show <= If this behavior meet expectation?

@testshallpass @wellyshen if alertWithType is not called from user interaction,message bar will not animate in.
It can reproduced by the following steps.
1.Set replaceEnabled={false}
2.call alertWithType() from a network callback or setTimeout 。

the fix is easy.I will send a PR

I was able to reproduce with a timeout as suggested. I have pinpointed the issue to it being the isOpen state variable being true when the alert is invoked from the timeout.
