Fix link stats

[OlivierHecart]

Description

This PR fixes a bug in link stats that caused link stats to be wrongly set to 0 in json reports.

What does this PR do?

Tis PR registers links in the stats registers with their complete src and dst locators including parameters.
Ex: tcp/1.1.1.1:1?prio=1 instead of only tcp/1.1.1.1:1.
This is needed as the links are then looked up with their complete locators when building the report.

Why is this change needed?

This fixes the json stats report.
