Fix unintended autosave on has_one through association
Fixes #35680
The problem occurred, when a `has one through` association contains
a foreign key (it belongs to the intermediate association).
For example, Comment belongs to Post, Post belongs to Author, and Author
`has_one :first_comment, through: :first_post`.
In this case, the value of the foreign key is comparing with the original
record, and since they are likely different, the association is marked
as changed. So it updates every time when the origin record updates.
