Purpose

Resolves issue 1822 - Removal of the last stored event in the InMemory table disrupts the references chain, subsequently causing improper behaviour within the InMemory table. Any future inserts are erroneously appended to the removed event, leading to unexpected and undesired outcomes.

Goals

Fix the logic of the remove method in the SnapshotableStreamEventQueue class to gracefully handle the removal of the last item. Reset the last variable to point to the previous item if the item being removed is the last one.
