fix: check first if object is null

[skrobek]

I wonder why $this->uploads in CollectionUploadSubscriber.php gives:

array( '0' => null );

Shall we first check if object is not null ?

 if ($upload === null) {
    continue;
}

When save a entity without images, got this error:

Call to a member function getFile() on a non-object in .../vendor/avocode/form-extensions-bundle/Avocode/FormExtensionsBundle/Form/EventListener/CollectionUploadSubscriber.php on line 160

So, your solution work it and make sense for me

The error you described was linked to the storage, not the upload parameter. Commit https://github.com/avocode/FormExtensions/commit/178ee272e8476c95ff81a84b4c55cf7e55592475 should fix this issue.
