Update of the status bar on the hide menu is now called at the completion

[thibault-carpentier]

This fix the bad update when switching form two contentViewController with different status bar colors.

When called alongside with a hideMenuViewController the statusBarNeedsAppearanceUpdate called outside the completion block of the hideMenuViewControllerAnimated caused the status bar to switch back to the previous contentViewController, since this is triggered before the completionBlock of the animation in setContentViewController.
