Drag & Drop of several documents to the DM portlet should be handled the same way the "Multiple Upload" option is in case two or more documents have the same file name: in this case, unique names must be autogenerated by Liferay.

Steps to reproduce:

1. Go to Documents & Media portlet.
2. Drag & drop a local file, called for example 'test.txt'.
3. Drag & drop the same local file.
4. Checkpoint: two files called 'test.txt' are added to the list of documents.
5. Refresh the page.

Expected result: no error is shown and two files called 'test.txt' and 'test (1).txt' are uploaded.

Current result: only the first document is uploaded and error "Your request failed to complete." is shown.
