LPS-28155 Fixes for Message Boards in Recycle Bin

Hey Julio,

This is a set of fixes for the Message Boards in the Recycle Bin. 

There are two pending issues which are not resolved within these fixes, because I think they might require further discussion:

* Improve current full-content asset templates (or generate specific ones for Recycle Bin) to include advanced information such as ratings, related assets and discussion. Jorge told me to remove this data from the content view in the RB portlet, even if we missed some functionality since it didn't look and work fine.

* Improve the restore dialog. This dialog is shown in case the restore cannot be executed (e.g. the original container does not longer exist) and a user's decission is required. It is currently working, but its behaviour differs from the move dialogs in the Document and Media or Message Boards. Maybe we should consider to unify criteria and improve the design of these dialogs (move dialogs look specially poor).

Since the above described issues affect to the general behaviour of the Recycle Bin, maybe we should open a new story for them.

Thanks!
