Don't clear translation state on temporary detachment.

Change I97cc418a8 broke translation on apps which use ListView; messages
were re-translated with the animation even while on-screen. A new
message arrival triggers a re-layout which causes the temporary
detachment, which caused translation to be cleared, and the views get
translated again later.

The solution is to NOT clear translation in the case of temporary
detachment. When Views are actually recycled (e.g., by ListView and
RecyclerView), the detachment is permanent/non-temporary.

Bug: 232178488
Test: atest UiTranslationManagerTest
Test: Manual - Verified scrolling and new messages arriving when
translation is enabled. Tested on apps that use ListView and
RecyclerView.
