Description

If a query targets an Iceberg metadata table like default.xy.`files` and the xy table is not an Iceberg table then the analyzer throws IllegalArgumentException. 

The main concern is that IcebergMetadataTable.java:isIcebergMetadataTable is called before it's validated that the table is indeed an IcebergTable.

Example: 

create table xy(a int);
select * from default.xy.`files`;
