Loop indicators do not update on score layout changes

Ubuntu 14.04, GIT commit: bbe146b

1) my first score
2) fill first measure with quarter notes
3) set loop in on first note, loop out on last
4) add line break after bar 2

Result: although the layout has now changed, loop indicators do not move, so loop out appears to be on the wrong note. They remain wrong through any and all edits until you turn the loop off then back on.

As far as I can tell this has been present all along - at least since the Beta. I'm a little surprised it doesn't seem to have been noticed. But I only foudn it as I was investigating #38991: Input cursor jump on up/down if accidental change causes layout shift and started studying the code wondering what else might be affected and decided to test the loop indicators. It appears there just isn't any code in place to update loop indicators after a layout.
