Fix for where.associated method join type override issue

Identified and resolved a critical bug in Rails ActiveRecord's where.associated method that was incorrectly overriding existing join types in complex queries. The fix ensures proper join type preservation (INNER JOIN vs LEFT OUTER JOIN) based on existing scope joins, preventing unintentional query behavior changes.

Technical Impact:
  • Fixed SQL query consistency issues for complex association filtering
  • Preserved existing join types when using left_joins with where.associated
  • Improved developer experience with more predictable query behavior
  • Enhanced compatibility across Rails applications using complex ActiveRecord queries
