Subject: Implement missing equals and hashcode methods for feeditem (#7132)

Till 5713b1826795598848c95f31df906b7af5ce7076 many classes like FeedItem
used to inherit from FeedComponent which provided those two methods.
However since that commit the component no longer exists and now the
classes need to implement it on their own. Without this, ArrayList.remove breaks.
