Fix narrow statusbar when folding

Do not re-create UnfoldMoveFromCenterAnimator
when attaching/detaching status bar view.
UnfoldMoveFromCenterAnimator contains
last transition progress state which is 0f
by default. When transition finishes last state
should be 1f but because animator was re-created
it was reset to 0f which caused applying translations
to the status bar items.

Test: unfold, fold, rotate to landscape =>
 statusbar displayed correctly
