Merge M59: "Start reporting watch time if ABR adapts above 200p."

Previously we only checked the initial resolution and assumed it
was always large enough to start watch time reporting; clearly
this is not true since YouTube offers a 140p format.

Probably we also want to drop the minimum resolution to 200x140p,
which I'll check with product about and handle in a followup CL.

BUG=711792
TEST=new tests. Manual: force 140p, adapt above, verify watch time.
