Actually, test tube holders are made out of a variety of materials, including wood, metal, and plastic. If all of the test tube holders in your school or lab happen to be made out of wood, it's likely because wood ones were the cheapest option available.
Also, just one more benefit is that if considering an exothermic reaction (producing heat) in the test tube, the wood rack would not become hot, unlike a metal one
