bug(background-mode): Promise callbacks never fired.

[ramoncarreras]

Hi,
I'm using @ionic-native/[email protected].

If I execute the following code, console does not show any log.

let bkgmodeConfig: BackgroundModeConfiguration = {
    title: this.translateService.instant("app.background-mode.notification-title"),
    text: this.translateService.instant("app.background-mode.notification-message"),
    color: "000000" ,
    icon: "icon"
};

this.backgroundMode.setDefaults(bkgmodeConfig).then(
    () => {
        console.log('[backgroundMode] setDefaults success');
    },
    () => {
        console.error("[backgroundMode] setDefaults error");
    }
);
this.backgroundMode.configure(bkgmodeConfig).then(
    () => {
       console.log('[backgroundMode] configure success');
    },
    () => {
        console.error("[backgroundMode] configure error");
    }
);
