Remove obsolete cookie consent IDs

[carlgieringer]

We removed Smallchat, but now I get this error in the console: Unsupported cookie consent id: live-chat. My cookie-consent-preferences local storage is:

[{"id":"required-functionality","accepted":true},{"id":"basic-functionality","accepted":true},{"id":"live-chat","accepted":true},{"id":"error-reporting","accepted":true},{"id":"full-error-reporting","accepted":true},{"id":"analytics","accepted":true}]
