task_statuses_task_owner_id_fk should not be FK

who is owner of the task is determined by task_owner_type. It can be systems, but it can be other table as well.
fix typo in name of table

addressing:
PGError: ERROR:  relation "organization" does not exist
: ALTER TABLE "organizations_users" ADD CONSTRAINT "organizations_users_organization_id_fk" FOREIGN KEY ("organization_id") REFERENCES "organization"(id) INITIALLY DEFERRED

and solving similar typos too.
