Fixed link not opening in a new tab inside phonebook page

[tonyco97]

Steps to reproduce

At this moment, if we position ourselves in the "Phonebook" section and select a contact with a url link, clicking the link will not open a new tab but it will open within the same page thus resulting in a wrong page.

Expected behavior

When you click on a url link of any contact in the phonebook, the latter will have to open correctly in a new browser tab
