Bug Description and Steps to Reproduce

Because the method pkg/common/storage/database/mgo/msg.go:SearchMessage did not filter out empty messages, it means msgs[index].msg maybe nil, it leads to:

1. There may be a NPE on line 168 of the method internal/rpc/msg/sync_msg.go:SearchMessage.

2. It is also incorrect that the query results contain empty messages themselves.
