fix: Reset all counter in metadata with purge for RequestQueue (#1686)

### Description

- Reset all counter in metadata with `purge` for `RequestQueue`. This
will be more consistent with JS. Also, saving the `total_request_count`
and `handled_request_count` counters causes confusion among users,
especially when this happens with the `default` queue.

### Issues

- Closes: #1682
