This fixes the flaky ALTER/CREATE tests by removing a verification step that didn't add value and was non-deterministic. The verficiation step that was removed verified that CREATE/ALTER set the appropriate file format by changing the format to something that didn't match the underlying data files, then attempting to read the data. This is already covered by the positive test case where the file format is changed to match the underlying data.
