Cannot setup sync (v2)

### Describe your issue

I'm trying to setup sync with a local taskserver running on a rpi. The server works just fine (tested with 2 laptops), but if I go into the app settings and add certificates and taskrc file (a copy of the one I use on the laptop, without `taskd.certificate`, `taskd.key` and `taskd.ca`), I get all green ticks but at the bottom the popup says "Please setup your TaskServer"

### Steps to reproduce

1. Go to Menu
2. Profile -> Manage selected profile -> Configure Taskserver
3. Add `taskrc` (as explained above)
4. `Configure Server Certificate` set to `ca.cert.pem`
5. `Configure your certificate` set to `first_last.cert.pem`
6. `Configure your key` set to `first_last.key.pem`
7. Press the lightning (?) icon in the top right corner
8. All green ticks
9. Popup at the bottom of the screen says "Please setup your TaskServer"

### What was the expected result?

Taskserver correctly setup and sync enabled

Reproduzca el problema mediante Menú > Perfil > Gestionar el perfil seleccionado > Configurar Taskserver utilizando los archivos taskrc y de certificado indicados. Rastree por qué la configuración muestra marcas de verificación verdes, pero sigue informando «Please setup your TaskServer»; se considera completado cuando se acepta el taskserver y se habilita la sincronización.
