[SPARK-46577][SQL] HiveMetastoreLazyInitializationSuite leaks hive's …

…SessionState

### What changes were proposed in this pull request?

The upcoming tests with the new hive configurations will have no effect due to the leaked SessionState.

```

```

As the logs above revealed, ThriftServerWithSparkContextInHttpSuite started the ThriftBinaryCLIService instead of the ThriftHttpCLIService. This is because in HiveClientImpl, the new configurations are only applied to hive conf during initializing but not for existing ones.

This cause ThriftServerWithSparkContextInHttpSuite retrying or even aborting.
