Macro databricks__get_columns_from_information_schema is not working as expected

[HantonMing]

Describe the bug
Unity catalog is disabled for us and we have trouble with dbt run -s elementary. In the macro elementary/macros/edr/metadata_collection/get_columns_from_information_schema.sql, another macor is defined for databricks ,which is databricks__get_columns_from_information_schema. The if condition in this macro,

{% if target.catalog is none %}
        {# Information schema is only available when using Unity Catalog. #}
        {% do return(elementary.get_empty_columns_from_information_schema_table()) %}
    {% endif %}

is not working properly in that if condition target.catalog is none is never met. In other words, return(elementary.get_empty_columns_from_information_schema_table()) is never executed. I know this because I made changes to rest of the macro, and changes were reflected in compiled query.
To Reproduce
Steps to reproduce the behavior:

1. Install elementary-data following instructions
2. Run dbt run -s elementary
3. Error message "Unity Catalog is not abled on this cluster"

Expected behavior
Disabled Unity Catalog should be correctly detected. And workaround macro is run.

Hi @HantonMing ,
Thank you for opening this issue and sorry for such a long delay in our reply.

I'm not sure if this is still relevant to you, but actually would love to know - you mentioned the condition target.catalog is none is never met.
Do you manage to see what value does it contain? Does it contain a legitimate value even though you are not using Unity Catalog?
