Video banner restarts video after 30-100ms

[ValentinTeqBlaze]

Describe the bug
The video outstream example loads the ad, starts playing, and after 30-100ms restarts it. We found out that the reason for this is VisibilityTrackerListener which starts the video after 30-100ms even if it is playing already.

As a result, we see 2 calls of the onAdDisplayed callback. Also sometimes it finishes AdViewProgressUpdateTask before the real end of the video. But this task is responsible for finishing the video using the VAST <duration> tag and updating progress view, so it doesn't have to finish.

To Reproduce

• Open the internal test app.
• Open "Video Outstream (In-App)"
• 2 callbacks of onAdDisplayed
