installation: mysql default date value fix
installation: mysql default date value fix

* Fixes problem while installing Invenio using fixtures where some dates
  were set with year=1, which is not accepted by mysql and this made the
  installation crash. Now, they are set to 1900 which is the lowest
  value accepted by MySQL.
