Issue with declaring bindings and singletons properties

Description

The commit ed28a45 seems to be creating an issue.

When they are magic properties, there is some wiggle-room for how they get defined. For example, in SquirePHP it gets defined with the data-type of array: https://github.com/squirephp/repository/blob/3.x/src/RepositoryServiceProvider.php

So this accidentally becomes a backward incompatible change unfortunately.

Steps To Reproduce

• laravel new bug-report --github="--public"
• composer require squirephp/countries-en

This results in the error:

PHP Fatal error:  Type of Squire\RepositoryServiceProvider::$singletons must not be defined (as in class Illuminate\Support\ServiceProvider) in /Users/manavo/Code/laravel-bug/bug-report/vendor/squirephp/repository/src/RepositoryServiceProvider.php on line 7

In RepositoryServiceProvider.php line 7:
