The notification's Accept button has carried EXTRA_ANSWER_CALL since it
was written, and nothing ever read it. Pressing Accept did what any
other tap did: it opened the app. Answering was left to the next turn of
the polling loop, which refuses a parked offer older than the caller's
patience, so a call taken a little late opened the app onto nothing and
looked like it had dropped the moment you answered it.
MainActivity reads the extra now, on a cold start and on a warm one,
and answers at once rather than waiting for a tick.
The notification also goes away on its own when the offer it shows has
expired. Before, it could outlive the offer by the gap between service
sweeps, which is longer since the loop started holding its poll open,
and during that gap it was a button that could only disappoint.
Seen on the emulator: Accept pressed, app opened, nothing on screen.
