Support for Safari

[nncl]

I am submitting a

• [x] Bug Report

What is the expected behavior?

Be able to get the user id through await OneSignal.getUserId()

What is the current behavior?

It returns a bug when subscribing as shown:

What are the steps to reproduce?

As far as I can see just creating the project as the example in the docs.

What is the use-case or motivation for changing an existing behavior?

Which versions are you using for the following packages?

Angular: 10.2.0 Angular CDK: 10.2.6 Angular CLI: 10.2.0 Nx (option): ngx-onesignal: 10.0.0

Is there anything else we should know?

This is my app.module:

NgxOneSignalModule.forRoot({
      appId: 'my-app-id,
      autoRegister: false,
      allowLocalhostAsSecureOrigin: true,
      notifyButton: {
        enable: true,
      },
    }),

And my app.component:

import { Component, OnInit } from '@angular/core';
import { OneSignalService } from 'ngx-onesignal';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {

  constructor(public readonly onesignal: OneSignalService) {
    (window as any).ngxOnesignal = this.onesignal;
  }

  ngOnInit(): void {
    setTimeout(() => {
      this.onesignal.subscribe();
      console.log(`Initiated`);
    }, 2000);
  }
}

Also, I couldn't see anything about the safari_web_id property as described in https://documentation.onesignal.com/docs/safari-web-push-setup, so, does this wrapper supports it?

My Safari version is 14.0 (15610.1.28.1.9, 15610) and I'm on a Mac OS Catalina 10.15.7.

You can access my example here https://onesignal-testing.surge.sh and also its repository on Github https://github.com/nncl/ngx-onesignal-test

I really appreciate your help :)
