scale: Make draw-value default to FALSE

Browse Source 
This is rarely what you want, so lets turn it off
by default.

Update the one place in our demos where we want to

add a test and mention this change in the migration
guide.

### Adapt to GtkScale changes
The default value of #GtkScale:draw-value has been changed to %FALSE.
