 Review comment:
   This PR prevents lookupTableFromCatalog from throwing NoSuchTableException 
right away. Instead, it relies on checkAnalysis to throw an exception for 
UnresolvedRelation.
   
   The test hive.SQLQuerySuite."double nested data" would fail in the following 
sql without this change:
   ```
   CREATE TABLE test_ctas_1234 AS SELECT * from notexists
   ```
   HiveAnalysis gets to run before checkAnalysis, thus exposing this bug where 
query.output is used before query is resolved.
   
   So wouldn't say it is a totally separate issue.
   In addition, outside of this PR, it'd be hard to write a unit test.
