Update service is unusable on 2.0.3

Commit https://github.com/xwiki-contrib/macro-fullcalendar/commit/4d1784615d7d776b6bb50691e321887ff17064f4 which is about formatting the sources of the full calendar macro seems to be introducing syntax errors in the UpdateService script.
This means that the update service will not work at all on Full calendar 2.0.3 .
