Steps to reproduce:
1. Log into any Alfresco DM space (any user)
2. Cut any content to clipboard
3. Navigate to any wcm project (user must be invited to web project first)
4. Browse users sandbox
5. Paste content from clipboard via shelf.
Expected result: content should be pasted to users sandbox (same operation succeeds for copy routine)
Actual result: content is not pasted (it's also not removed from source space)
