Allow restore from trash search

Steps to reproduce:

• Create two documents in a folder.
• Select both documents from the folder and click on the delete icon to trash them.
• Go to the trash search (from the left menu, not the tab).
• Search for the trashed documents by entering the Author.
• Select the two documents from the search results.
  => Blue bar at the top no longer includes the Restore icon.

No errors in browser console or server logs.

Trashed files can still be restored from the trash tab on the parent folder.
