Ryuta Kamizono 0e76553934 Maintain extra joins for string or complex arel conditions
49bcb00 has changed to maintain extra joins only if other table's
condition is found (e.g. `other_table[:id].eq(table[:foreign_id])`).

It means that cannot maintain extra joins for complex conditions
(especially "(... OR ...)"), so it has caused a regression #37167.

This changes to maintain extra joins for complex conditions too like as
before.

Fixes #37167.
