ARROW-16085: [C++][R] InMemoryDataset::ReplaceSchema does not alter scan output Feels a little funny that deleting this code just makes it work, so I added a decent number of tests to make sure differing schemas are handled. LMK if you think I missed something. Closes #13088 from wjones127/ARROW-16085-unify-inmemory-datasets Authored-by: Will Jones <willjones127@gmail.com> Signed-off-by: David Li <li.davidm96@gmail.com>
