Fix service call for setting a config value about certification-backlog

[AlCalzone]

Also, resetting all config parameters (and optionally, individual ones) to default must be supported.

This is not supported yet

Refreshing such a config parameter seems also not supported, this is not a requirement though.

This task has been split up into multiple smaller ones. Left is fixing the set config value service call.

@AlCalzone according to the typing here: https://github.com/zwave-js/node-zwave-js/blob/master/packages/cc/src/cc/ConfigurationCC.ts#L107

valueFormat is required alongside valueSize. Is that correct? If so then this behavior is correct and should be expected. If not, then should we update the type? This will need to be fixed in the server and lib as well

Hmm, you're right. I could have sworn it defaults to signed. In this case it's just the error message that's terrible.

Yeah unfortunately that comes from the validator we use. I'll look into customizing the message
