ERP5Site_updateTranslationTable has to be called when new translations are
added.
We also need to cleanup after each test, not to get persons created in other
tests, this revealed a bug in ERP5Site_checkDataWithScript, it was getting
objects created in the previous test, the test was not failing though, because
previous test objects have the same urls
