Fix wrong labeling of app launch session type (HOME vs OVERVIEW)

Context: onResetOverview callback should be called the moment launcher state
exits from OVERVIEW.
More context: When user drag and drop from overview, and happens to launch
an app immediately after dropping the icon before animation finishes,
that app launch is labeled as OVERVIEW and not HOME.
