Showing starting window after activity flags applied

Starting window was shown while brought an existing task to front and
that had increased Phone hot launch time.

Before bde91e9, a single-task activity (like Phone) had the new intent set
in earlier flow and the snapshot starting window was not allowed to show if
an intent (other than main) had set, see AR#allowTaskSnapshot(). So, there
was no starting window during hot launch.

Showing starting window after activity flags are applied, where the
new intent (if any) were set, and doing so if the task had moved to front.
