FIX: Unlike own posts on ownership transfer (#10446)

* FIX: Unlike own posts on ownership transfer

If a user has liked a post that has passed the
`post_undo_action_window_mins` system setting window and you transfer ownership
of that post to that user you will be the owner of a post that you have
liked, but cannot unlike resulting in a weird UI behavior. This commit
fixes this issue.

The existing tests didn't check for the timeout window for unliking
posts so I added that in.

I couldn't find a good way to do this logic inside of the guardian class
so rather than duplicating behavior of the `PostActionDestroyer` class
inside of the `PostOwnerChanger` I decided to pass in a "bypass"
variable that could be used to check if the calling class is the
'post_owner_changer' and bypass the guardian instead. I went this route
because the guardian `can_delete_post_action` method has no way of
distinguishing how to allow a user to be able to unlike their own posts
after the timeout window but only on a post owner change.

* use an options hash instead
