So am I!
I'm quite sure it was the Teselecta all along. He didn't change his fate, his fate was what it always was. We just saw it from Amy's POV the first time, and then the events leading up to it the second time. There's no alternate timeline where the Doctor did the exact same things in the exact same order but didn't think to speak to the Teselecta and so actually died - he piloted the Teselecta before the timelines ever diverged. My impression is that the Teselecta always burned in that boat, and the Doctor always piloted the TARDIS to safety. (Along, presumably, with the crew of the Teselecta.)
The timeline reasserts itself at the end, so the events we see are the events we always would've seen. It's just that we, like River, have learnt that everything's going to be okay, and that events are allowed to assert themselves. That's our journey.
