fix(use_self): descend into type's children when looking for lifetimes

This unfortunately breaks another test case -- it had only worked
because when we checked `!has_lifetime` on `S2<S<'a>>`, we only looked
for generic lifetime params on `S2`, forgetting to descend into `S`.

One thing that makes this a bit less sad is that this particular test
case doesn't come from a reported issue, but rather was added as a
miscellaneous check during a kind of unrelated PR.
