loleaflet: Exit early for invalid commandvalues
LO core doesn't output any change tracking information for spreadsheets
which results in sending an empty 'commandvalues: ' message to
loleaflet. While the actual fix for it would go in LO core, lets handle
this empty case for now in loleaflet, so that we don't throw any runtime
JS exceptions.
