I've implemented this for now in the attached patch and am currently 
testing it.  Initial results suggest it resolves the problem.

It introduces a new method, NotePairs::appendAndReplace(), which 
iterates through the source NotePairs and removes any NotePairs in the 
destination that have the same key, then calls append().

This is not the most efficient way of erasing the notes, because Squid's 
Vector template doesn't appear to have an erase() method.
