Subject: [PATCH] Setting _schema rather than replacing it

[CT-276] Apache Iceberg Support #294

The _schema variable was used for non-iceberg tables but was being
overridden by work for iceberg v2 tables.  I've made it so the iceberg
condition will set _schema rather than blanket changing the schema for
all providers.
