Fix i18n warning
Do not pass a null translation domain, use the API as recommended by KAboutData's documentation.
Fixes the following warning: Using an empty domain, fix the code. msgid: "Your names" msgid_plural: "" msgctxt: "NAME OF TRANSLATORS" Using an empty domain, fix the code. msgid: "Your emails" msgid_plural: "" msgctxt: "EMAIL OF TRANSLATORS"
CC @ltoscano @aacid, as I don't know why we would have done it in this weird way before.
