Michal Terepeta e8acf49088 Fix a corner case when printing unaccounted time
Previously `ra_prof` wouldn't actually print the unaccounted time in
some cases.

We would print, for instance, this:
```
    5ms - foo
        2ms - bar
```
instead of:
```
    5ms - foo
        2ms - bar
        3ms - ???
```

The fix is to properly handle the case when an entry has 0 children
instead of using the `last` variable.
