Review Comment:
   I feel like this unnecessarily duplicates the tests that are being done in 
https://github.com/apache/iceberg/blob/main/core/src/test/java/org/apache/iceberg/view/ViewCatalogTests.java#L77
   
   The only difference here is that you're also checking view existence with an 
invalid identifier
