The issue is visible when reconfiguring the screen arrangement while
sharing the displays. Can sometimes be seen right after starting the
screen sharing.
Indeed CaptureFrame can be called at any time so TakeLatestFrameForDisplay
should always return a valid frame and the call should not empty the
internal container.
Also add missing teardown in the provider on failure case.
