SUMMARY

Preshared keys added to a wireguard peer after creation through the System Settings UI do not properly work (don't persist and aren't used).

STEPS TO REPRODUCE
1. Create a wireguard connection with one peer, don't add a PSK to said peer
2. Save the connection
3. Edit the peer to add a PSK
4. Save the peer and connection
5. Enable the connection

OBSERVED RESULT

`wg showconf` does not list the Preshared key and the connection does not work.


EXPECTED RESULT

`wg showconf` lists the Preshared key and the connection does work.
