Review Comment:
In a previous PR I added this test case. It works without providing the
schema (with the current change) and we don't need the change I did in the
`_ensure_scheme`. But if a user provide a schema in this method, I get nulls
for the `exp_meta` column after making this change. That was the bug
encountered. I wasn't quite confident changing the test case to make things
work. Do you agree with the C++ change to fix this bug? If so, for Python we
could just leave the `schema`, but in case someone provides it there, we could
run into trouble.
