[FR] Ignore "cf" when pointing to special pages

[BoboTiG]

• Wiktionary page: https://fr.wiktionary.org/wiki/batinse

Wikicode:

{{cf|:Annexe:Sacres québécois}}

Output:

→ voir <i>:Annexe:Sacres québécois</i>

As the link refers to the current page, it may be better to simply ignore such case?
Maybe a simple check could be to render an empty string when the arguments starts with ":" 🤔
