Iceberg: Branches with non-lowercase characters can't be accessed

Repo:

1. Let's create a branch

ALTER TABLE Devices CREATE Branch Sandbox

2. Check the existence for evidence

SELECT * FROM `default`.`devices`.`refs`;

The References show it properly

3. Select from branch

SELECT * FROM default.Devices.branch_Sandbox;

But if the select it would throw an exception:

Error while compiling statement: FAILED: SemanticException Cannot use snapshotRef (does not exist): sandbox

I guess the select operator does have a simple equals and does not check the cases also the cultureInvariant could be a different issue

Exception
