Use newly added InvalidCommandId instead of 0

Browse Source 
The symbol was added by 71901ab6d; the original code was introduced by
6868ed749.  Development of both overlapped which is why we apparently
failed to notice.

This is a (very slight) behavior change, so I'm not backpatching this to
9.4 for now, even though the symbol does exist there.
