    this.userEmail = info['email'];
    this.userName = info['displayName'];
    this.userUid = info['uid'];

Should be aware that you are using an asynchronous function and you should insert the record into database after successful sign in.

loginWithFacebook() {

    this.facebook.login(['email']).then((response) => {
        let credintial = firebase.auth.FacebookAuthProvider.credential(response.authResponse.accessToken);
        firebase.auth().signInWithCredential(credintial).then(info => {
            this.userEmail = info['email'];
            this.userName = info['displayName'];
            this.userUid = info['uid'];
            this.afDatabase.database.ref(`dump/${this.userUid}`).set({
                username: this.userName,
                email: this.userEmail,
                uid: this.userUid,
                wallet: 0
            }).then(data => {
                this.navCtrl.setRoot(TabsPage);
            });
        });
    });

}
