Remove writable eduroam check loop

Remove a loop between get a event that eduroam is connected and trying to write at the eduroam configuration. After writing in the eduroam configuration, the eduroam reconnects. A reconnect firers a new event and let the app checks all configuration. In case of checking the configuration the eduroam config will be written.

If App detects, that the eduroam configuration is writable, it will remember and will no longer perform a check.
