Fix for MDM in case ovpn field is one line

Fix for MDM which support appconfig (in case ovpn field is one line base64 encoded string).

If config contains only one line without spaces, then:
- If not exception is cought, then it is a decoded base64 string
- If exception is cought, then assumed it is a normal string
