Investigate "column name is ambiguous" normalization errors

[grishick]

We are seeing several instances of SQL errors coming from SQL generated by DBT complaining about Airbyte internal column names being ambiguous:

• column reference "_airbyte_normalized_at" is ambiguous
• SQL compilation error: ambiguous column name '_AIRBYTE_AB_ID'
• column reference "_airbyte_ab_id" is ambiguous
