Mac: Safely dispose of scrollbars temporary NSGraphicsContext
When rendering transient scrollbars, we instanciate a specialised
NSGraphicsContext since those need non-opaque rendering. This context
is being used as current context, but it was never properly released
and the previous context never properly restored.
Task-number: QTBUG-27327
