Subject: [PATCH] Wrong exception class: ActiveRecord::RecordNotUnique, not
 PG::UniqueViolation (#7688)

* Wrong exception class: ActiveRecord::RecordNotUnique, not PG::UniqueViolation

It's completely not obvious but PG::UniqueViolation is just a string inside the exception message, not the actual class of the exception

* Favourite does not have target_account_id
