Storage cleared everytime the app closes/on refresh

I'm using `@ionic/storage` v2.2.0 with Ionic v4 and Angular v7, and in development mode, the storage (IndexedDB in that case) is cleared on refreshing the page.

On mobile (with Cordova on Android v7.1.4), the storage is cleared upon closing the app.

I use NO extra settings in my app for the storage and used it just like the instructions [here](https://ionicframework.com/docs/building/storage) (I installed the npm package and the Cordova plugin).
