What is the classification for animals with full tube digestive tracts?
Animals with a single hole do not form a monophyletic group: metazoa > eumetazoa >bilateria almost all have separate mouth and anus (except notably flatworms which is one reason it does not form a monophyletic group).

As species are not grouped in monophyletic groups by what they don't have (eg. invertebrates do not form a monophyletic group while vertebrates do) there is no particular group. Eumetazoa before the bilateria have a single mouth-anus.
