Fix accessibility initialization

If accessibility is already enabled at construction time, QQuickControl
does not get a notification of accessibility activation change. This
patch fixes the issue that the attached property object was not created
at all, by calling accessibilityActiveChange(true) when appropriate at
component completion.
