Speeding up pins again

[robertsonbrinker]

Two things were done to speed up Pins:

1. Running GenerateData in a Task.Run was really slow because GenerateData had operations that required using the UIThread, thus putting that whole operation on the UIThread (which has other stuff to do) adding 30% more time. I broke up the GenerateData method into smaller chunks and only ran operations that don't require the UIThread in Task.Run

2. There was some unnecessary looping and duplicate calls of BookChapterVerseViewModel.GetBookNumFromBookName in the area where SortRefs is used. I consolidated some loops and duplicate calls
