Deal with the Error Messages

Error messages such as the following is spammed every time a configuration tab is open:
```
file:///home/attacktive/.local/share/plasma/plasmoids/xyz.attacktive.nyan-wanderer/contents/ui/config/configMovement.qml: Setting initial properties failed: Page does not have a property called cfg_mirrorImageDefault
```

I believe it can be safely ignored but still...
