FIX: Rename delete_when_reminder_sent? bookmark method to avoid conflict with AR (#10333)

I added delete_when_reminder_sent to ignored_columns because it no longer exists and added a shortcut method delete_when_reminder_sent? to the Bookmark model. However I have been seeing some weird errors like:

> Job exception: unknown attribute 'delete_when_reminder_sent' for Bookmark.

So I am very suspicious. I am just renaming the method to auto_delete_when_reminder_sent? to avoid any potential conflicts.

Also found include_bookmark_delete_on_owner_reply? in PostSerializer which is used for nothing; I must have forgotten to delete it before.
