This is needed because the NOT NULL constraint causes a conflict with some versions of MySQL configured with sql_mode=NO_ZERO_DATE, which can for instance lead to tables not being created.

Most other schema updates happen via ActionScheduler_Abstract_Schema::update_table(), however that method relies on dbDelta() and this change is not possible when using that function.
