Fixing a reloading issue and a typo (#221)

* Fixing reloading issue

After reloading the list of avatars as images was a tuple of the list of images and the list of avatar names.

* Fixing typo in is_new_frame_better

Probably the global predictor was used and therefore no error was produced when alievk tested the function.
