PS-1675 #comment Reordered vapid handling code on Android #time 1d

Native player preSequence needs to an unlocked video tag element in
order for vapid to work - this handling caused player event propagation
to be misaligned between android and rest of devices.
Moved specific vpaid handling to vpaid handler in kAdPlayer and aligned
android behaviour with rest of platforms.
