[O] [Feature Request / Bug] Remove statistic cookies from refile candidates

[Marcin Antczak]

I set up my refile targets and this is what I get when I'm trying to 
refile something from notes.org.

```
Refile subtre "Test" to (default devel.org/Project): devel.org/[0\0][0%] 
Project
```

Is this possible to remove automatically these statistics cookies from 
completion candidates list?

I know that I could write some custom function to list refile targets 
but this option could be available by default.


Regards,
Marcin
