Deflake simulcast flow tests: prevent negative Timestamp exception.

These tests often fail in 'ExtrapolateLocalTime' because the result gives a negative Timestamp.

Here is the stack from https://chromium-swarm.appspot.com/task?id=6173230e67897b10:
PC: @     0x7f03afdb8e87  (unknown)  raise
    ...
    @     0x55f4a360ba71        352  webrtc::Timestamp::operator+()
    @     0x55f4a47ecaf3        160  webrtc::TimestampExtrapolator::ExtrapolateLocalTime()

Low-Coverage-Reason: coverage isn't that low.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See here for instructions on how to get started developing with the native code.
