FIX: prevents i18n helper to return a SafeString (#9191)

For convenience the i18n helper has been made returning a SafeString, but when used with other helpers, a String is expected and will cause unexpected behaviors.

This is the root cause of the initial bug fixed in d2bb127e2c

This commit is kept as it's a better security in case of unexpected behavior.
