Coral-Schema alias output upper-cased schema even if I explicitly alias to lower case

To reproduce this issue:

add this test in ViewToAvroSchemaConverterTests and run it:

  @Test
  public void foo() {
    String viewSql = "CREATE VIEW v AS SELECT id as id FROM basecomplex";
    TestUtils.executeCreateViewQuery("default", "v", viewSql);

    ViewToAvroSchemaConverter viewToAvroSchemaConverter = ViewToAvroSchemaConverter.create(hiveMetastoreClient);
    Schema actualSchema = viewToAvroSchemaConverter.toAvroSchema("default", "v", false, false);

    System.out.println(actualSchema);
  }

the output will be:

{"type":"record","name":"v","namespace":"default.v","fields":[{"name":"Id","type":"int"}]}

Which shows the column name is Id rather than the explicit lower-cased alias: id.

Add the reproducer to ViewToAvroSchemaConverterTests and run it to observe the generated schema. Start at ViewToAvroSchemaConverter.toAvroSchema, then compare the output field name with the explicit id alias. Done means the generated schema preserves the lower-case alias.
