Fix the higlighted settings not work properly from search

Since the Andorid S, we introduce the CollapsingToolbarLayout
, the highlighted funcation might break for unkown reason.
I observed that broken cases with overlapping issue on tool bar.
The possible root cause is the interation bwtween
CoordinatorLayout v.s CollapsingToolbarLayout v.s Recycler
view.

This cl is definetly a workaround to prevent this issue.
I try to collapse the tool bar with an animation before
we start to scroll the list. This makes the overall transition smooth
but always collapse the tool bar.

Fix: 177968297
Test: Click a lot of search results, and screen should highlight
settings correctly.
