fix(core): handle elements with local refs in event replay serializat…

…ion logic

Previously, the event replay serialization logic was located before we verify that a `TNode` exists. `TNode`s may not exist in `tView.data` array in several cases, including cases when there is a local ref used on an element: in this case an extra slot in `LView` contains a reference to the same element and `TNode` is not needed. This commit moves the event replay serialization logic a bit lower, after we check for TNode presence.

Resolves angular#56073.
