Fix render of Documents in nuxeo-data-table of Folderish after importing 2+ documents

Steps to reproduce:

1. In Web UI, create a folder or workspace
2. Navigate to Create Button (bottom right) > Import tab. Drag and drop 2 or more different assets into the dropzone.
3. Click the "Create" button at the bottom right of nuxeo-document-import to create the documents in the current folder.
4. Observe only one document among the 2+ created is visible in the folder (corresponding to the first file selected for import).
5. Refresh the page to display all 2+ documents created.

Expected behavior: All created documents should be visible in the folder upon creation, without a browser refresh required to display them.
