MMS: Still in compose page after deleting the last message of conversation

After deleting the last message of the this conversation, the thread will
get deleted by a trigger in the database. If we still use the current
conversation to send SMS, this will cause the UI can not query out the
data in this conversation.

Add start query message list after deleting message in action mode. If we
just deleted the last message of the conversation, it will return to
ConversationList page.
