Fix preference copy migration and incorrect HDR+ sticky bit

A sticky bit upgrader particularly for HDR+ was looking in
globals but was actually a module setting. The copy migrator
was not properly handling booleans! Modified the copy migrator
to properly handle supported types and removed the custom
incorrect upgrader.
