Don't hardcode to \MABI\Identity\User in SessionHeader middleware
After saving or inserting, don't reload propertyArray (which doesn't have external fields)
pass $resultArray by reference
keep possible generated ID from save operation
move lastAccessed logic out of loadUser
use whatever ID property the model uses
