Fix wrong sync message issue for pending outgoing messages

If sync operation is occurred between ResendMessageAction and
SendMessageAction, the pending outgoing messages in local db are deleted
and new messages are added from remote db.

To fix this issue, ResendMessageAction will update RETRY_TIMESTAMP only.
And RECEIVED_TIMESTAMP and SENT_TIMESTAMP will be updated in
SendMessageAction when the message is queued.

Test: manual
