@Fokko @kevinjqliu, this one is ready for a review.
`SqlCatalog.namespace_exists` uses `LIKE '<namespace>.%'` to detect child
namespaces, and SQLite evaluates `LIKE` case-insensitively, so with only
`sales.eu` in the catalog `namespace_exists("SALES")` returned True and
`create_table("SALES.orders")` succeeded in a namespace that does not exist
(closes #4163). The fix keeps the `LIKE` filter and re-checks the matched names
with a case-sensitive prefix comparison in Python, the same way
`list_namespaces` already does.
