invalidatesTags - minor improvement

[croraf]

I want this logic in invalidatesTags:

invalidatesTags: (_, __, body) => {
        return body.meetingId ? ["Meetings", "Meeting Item"] : ["Meetings"];
      }

but maybe would be nice if in the returned array falsey values get ignored, so I could then write:

invalidatesTags: (_, __, body) => {
        return  ["Meetings", body.meetingId && "Meeting Item"]
      }

Or at least throw an error, because in this latter variant no error is thrown but the Meetings dont refresh.

P.S. I mean, I guess I can chain the returned array with .filter(i => i)

That seems like a reasonable idea :)
