Launcher3: Fix launcher ui interface overlap and frozen problem

Press recent key and quickly click recent screen background, then
Recent List task doesn't disappear and overlaps on Homescreen.

When there is no time for Background State to change to Overview State, and gotoState(Normal) API is called, then let Background State transition to Normal state, and force Normal state to not transition to Overview state.

Bug: 287897684
Test: manually
1. Launch any app
2. Press Recent key
3. Click on same app task on recent list
4. Press Recent key
5. As soon as recent list appears, quickly click on background of Recent screen
