[Taskbar icons unfold animation issue] Do not take into account initial translation

Browse Source 
Removes taking into account initial translation in
move from center animation. Initially it was done
because in StatusBar items are aligned using translations
but we decided to use different approach there so it is
not necessary anymore.

Now move from center animator can only set translations
from positive/negative value when progress is 0 and sets
it to 0 when progress is 1 (previously it was 'capturing'
the initial translation and animated the translation to
its original value).

Taskbar icons are pre-aligned using translations when
user is on launcher. After several folds/unfolds these
translations were accumulating that led to incorrect
positioning of the icons.

Found one more issue that we didn't clear the animated
views list after finishing the animation in taskbar unfold
animation controller but it didn't affect the animation
itself.

Test: atest com.android.systemui.shared.animation.UnfoldMoveFromCenterAnimatorTest
Test: unfold on launcher and use gesture nav to swipe to an app
