Fix issue with french translation
Initial white space was missing in both msgid and msgstr of the french
translation, leading to checking tools reporing an incomplete
translation. The string is a raw key id, and therefore did not need
translation, so this was never a user-visible issue.
* debian/po/fr.po: Add missing whitespace to the id and translation
for msgid " ${key_id}".
