Pawel Kozlowski ea8c9b61d2 fix(core): properly update collection with repeated keys in @for (#52697)
This change fixes a bug in the new list reconcilation algorithm
that could lead to an infinite loop in certain situations.

More specifically, it adjusts the internal MultiMap implementation
such that an entry returned from the .get call is the same entry
(for an identical key) removed by the .delete call.

The existing logic of the MultiMap was leading to a situation where
one view was requested and attached to LContainer, but a very different
view was removed from the MultiMap. This was leaving an attached LView
in a collection that was supposed to hold only detached views.
