Schema is not updated when using the same name

### Description

When setting the schema with `setSchemaFromShowSchema()` the schema is not updated in the kusto worker if the schema uses the same name as before.

### Steps to Reproduce

1. set a schema with name 'Default' with `setSchemaFromShowSchema()`
2. Update the schema with name 'Default' with new OrderedColumns of a table
3. Run `setSchemaFromShowSchema()` again with the updated schema
4. Schema is not updated!

```
monaco.languages.kusto.getKustoWorker().then(workerAccessor => {
const model = this.editor.getModel();
workerAccessor(model.uri).then(worker => {
worker.setSchemaFromShowSchema(schema, '', name);
});
});
```

**Expected behavior:** I expect that the schema is updated with the new columns

**Actual behavior:** Schema is not upedated

**Reproduces how often:** 100%

### System configuration

monaco-kusto version: 10.0.4
monaco-editor version: ^0.37.1

Start by reproducing the issue through the Kusto worker's setSchemaFromShowSchema() call, using the two schemas described in the steps. Trace how the worker handles a schema named Default when its OrderedColumns change, then verify that a second call exposes the updated columns.
