Update LocalForage dependency

[salbahra]

This solves #133 by giving developers the ability to monkey patch the instance. Once this PR is approved the following code would allow IndexedDB to work on Safari 10.1+ when using Ionic.

import { Storage } from "@ionic/storage";

constructor( private storage: Storage ) {
        this.storage.ready().then( ( localForageInstance ) => {
            localForageInstance.getDriver( localForageInstance.INDEXEDDB ).then( ( driver ) => {
                if ( driver._support ) {
                    this.init();
                } else {
                    driver._support = true;
                    return localForageInstance.defineDriver( driver ).then( () => {
                        localForageInstance.setDriver( localForageInstance.INDEXEDDB ).then( this.init.bind( this ) );
                    } );
                }
            } );
}

private init() { console.log( "Loaded!" ); }

Hello,
I have the same problem with safari.
Where should I add this code in an Ionic 3 project ? One in app.ts ? or before each call ?

Thanks for your help

@vptcnt I am using a shared provider to wrap Ionic storage so I am only doing this once.

After spending hours of my time I found #101 shows the exact same thing. Why is this taking so long to address when a compatibility layer is offered?
