Fixing bug with changing text size #3159

Bug appeared after 046940f but it was there before - it was just kind of compensated by the other bug.
Because of that bug blender text size value was reupdated before saving it to pset therefore pset never received a new value.

Also added some refactor, planned to write some test to get this error covered.
