That's an interesting hypothesis. But I don't buy it, certainly without some scientific testing (versus emotional, speculative anecdotes from people with dogs). Evolution doesn't work like leveling up in a video game. Once a local maximum is reached, further generations have no impact. I would also wager that, while there may have been some selection pressure to "read" a person's immediate emotional state, selection pressure for reading general personalities, etc. was likely much weaker. And, of course, the selection pressure for humans to "read" other humans would have been much, much greater. After all, we have to mate with each other. Dogs don't have to mate with us. They do, however, have to mate with other dogs, and interaction with other dogs probably dominated the selection pressure on dogs' social intuition faculties. So, I would speculate people are likely better judges of people than dogs are.
What probably happened with the schizophrenic people was perhaps they were anxious, because of delusions or whatever, and the dog picked up on that. You probably also did. That you had a single negative interaction with one person your dog didn't like is not an important piece of information, if we're going to go about this scientifically. But, hey, I'm speculating too. Someone would have to research this. How and why, I have no idea. But my speculation can beat up your speculation
