App share was deprecated in laravel 5.4. Using app singleton.

[whoacowboy]

You master was off from the tag so I made a new branch, laravel5.4.

I changed one line of code because app->share was deprecated in 5.4 for app->singleton.

---

share Method Removed

The share method has been removed from the container. This was a legacy method that has not been documented in several years. If you are using this method, you should begin using the singleton method instead:

$container->singleton('foo', function () {
    return 'foo';
});

This should be a priority. The fix takes few seconds to implement, but is indeed breaking.
I did the same change in our production app, and tests are passing again.

I'm also waiting for this PR to be accepted, thanks !

Guys, @maknz said on twitter that he doesn't have time to maintain this package anymore and will soon post a deprecation notice.
