[FIX] mail: display both tracking values and body of the messages in …

…mail thread

Before that, the body of the message was never displayed if the message had tracking values. This was annoying for account_asset module, were we prompt the user for some justification when she modifies the depreciation data of an asset, and then call message_post with this text as body, and tracking values reflecting the change that was made.
