runes: fix weird unnecessary zero-test. 

This seems to be a cut & paste bug (mine, AFAICT!) from the command code:

```
	rune = rune_derive_start(cmd, master_rune,
				 tal_fmt(tmpctx, "%"PRIu64,
					 rune_counter ? *rune_counter : 0));
```

In that case, rune_counter was a pointer, which could be NULL.
