On 4.14.0 I wasn't able to send knotes notes through network from one knotes to another.
When trying to send a note the akonadi_notes_agent receiver process displays this message:

  Object::connect: No such signal NoteShared::NotesNetworkReceiver::noteReceived(QString,QString)


Reproducible: Always

Steps to Reproduce:
1. Configure KNotes on the receiver computer to Accept incoming notes
2. If necessary open TCP port 24837
3. From the sender computer use the KNotes "Send..." function and send a note specifying the receiver IP address

Actual Results:  
Nothing happens on the receiver.

Expected Results:  
Have the remote note added to the notes on the receiver computer.

I've fixed it with the following patch:
