SUMMARY
When using wayland the shared clipboard function doesn't work at all.

STEPS TO REPRODUCE
1. Be sure kdeconnect "shared clipboard" function already works well under X11
2. Start a new Wayland session
3. Copy some text on pc or on the mobile phone, or both.

OBSERVED RESULT
What is copied on the pc remain on the pc. What is copied on the mobile phone remain on the mobile phone.
>Bonus: if you have two phones connected on the same pc, when you copy something from phone A it will appear in the clipboard of phone B, but not on pc.

EXPECTED RESULT
When copy something in the phone clipboard should be seen on pc clipboard and vice versa.
