URL: https://github.com/apache/doris/pull/45521
If we set lower_case_table_names to 2, and then create a catalog with meta
cache. The `lowerCaseToTableName` in `ExternalDatabse` will be empty because
`listTableNames` method is invoked in meta cache. Now, if we directly execute
`getTableNullable`, we will get null.
### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #38227
Problem Summary:
If we directly query a table after the catalog creation, we will get a
AnalysisException with table not found message.
