Fix search highlight issues

This cl fixes two kinds of issues.
1) Highlight two different preferences while clicking a search result.
2) Preference only is  highlighted one time.

For the first problem, we don't allow to reuse view holder in the
highlight scenario, and then allow it later.

The root cause of second problem is scrolling to target preference
needs x milliseconds. Thus, we should wait a few milliseconds, and
then start to highlight preference.

Test: Test some search results, and see the correct behavior
