Title: replaces id generated by random uuid with new ObjectId().toString()

UUID is too long and prevents deletion of a document form the database

see:

de.taimos.dao.mongo.AbstractMongoDAO.delete(String)
and
http://docs.mongodb.org/manual/reference/object-id/

The problem still exists, when setting the id manually with a value not conforming to a ObjectId.
