[IMP] mail_bot: remove required on odoobot_state

Purpose is to avoid having strong requirements on fields where it is not
really necessary. In this commit we consider now that a void odoobot_state
is the same as ``not_initialized`` key. It allows to remove both the default
and required parameters on the field.
