Add MsgId.trash() and use it to delete messages locally

Browse Source 
In addition to moving the message into trash chat, this function
removes message text to make sure the message does not remain in the
database. Only the information necessary to delete message from the
server and avoid redownloading it should be kept, such as Message-Id
and IMAP UID.
