[BUG] - Search domains disappear from DNS setting of WireGuard tunnel

[dsh2dsh]

Describe the bug
Search domains added to the DNS setting are not restored when editing the config, thus are lost on next save unless entered again each time.

Smartphone (please complete the following information):

• Device: Samsung S21
• Android Version: Android 14
• App Version: 3.5.2

To Reproduce
Steps to reproduce the behavior:

1. Go to the tunnel config editor.
2. Add a search domain to the DNS input, e.g. 10.5.5.1 -> 10.5.5.1, mydomain.example, so that queries for machine are first qualified to machine.mydomain.example.
3. Save the config.
4. Open the same tunnel's config.

Expected behavior
The input should contain the search domain but only has the DNS server IP(s).

Additional context
This is a copy-paste of #233, because I can't add my comment there, but I've got the same problem using latest release.
