TUN-8762: fix argument order when invoking tracert and modify network info output parsing.

## Summary

The windows code path has three bugs:

* the -4 and -6 option cannot be passed in the last position
* since there are some lines in the command output that are not parsable the collection fails to parse any kind of output
* the timeout hop is not correctly parsed

This PR also guards the parsing code against empty domains

Closes TUN-8762
