createUserWithEmailAndPassword exception propagates to global handler

### Version info

**Angular:**
angular/core: "~13.1.0",

**Firebase:**
"firebase": "^9.6.3",

**AngularFire:**
angular/fire: "^7.2.0",

**Other (e.g. Ionic/Cordova, Node, browser, operating system):**
Windows 10, Node.js v16.13.2., Edge and Chrome, latest version

### How to reproduce these conditions
Using the ``compat`` layer

```
import {AngularFireAuth} from '@angular/fire/compat/auth';
// etc

// choose an email address that is already in use, this throws the exception auth/email-already-in-use as expected
this.angularFireAuth.createUserWithEmailAndPassword(email, passwd).then((userCredential) => {
// user create was successful
}).catch((error) => {
console.log(error);
// even though we catch auth/email-already-in-use
// the error still propagates to the global error handler
// and appears on the console
// see the screenshot
});
```

** Screenshots **

### Expected behavior

The exception that is caught in the catch block should not make its way to the global error handler

### Actual behavior

The exception that we caught in the catch block still propagates up to the global error handler

@angular/fire/compat/auth のエントリーポイントから開始し、すでに登録されているメールアドレスを使って createUserWithEmailAndPassword で問題を再現します。捕捉された auth/email-already-in-use エラーを追跡し、promise catch の動作をグローバルエラーハンドラーと比較します。捕捉された例外がグローバルエラーハンドラーやコンソールに到達しなくなれば完了です。
