Jean-Noel Avila c3027be9d1 i18n: remove i18n from tag reflog message 
The building of the reflog message is using strbuf, which is not
friendly with internationalization frameworks. No other reflog
messages are translated right now and switching all the messages to
i18n would require a major rework of the way the messages are built.
