removed calling checkActive for connected local streams

[samgabriel]

fixes #606 connected streams should not be recycled as a reference is kept inside some webrtc libraries. The library will use the same MediaStream to publish another track if the user decides to do so causing an error of pluginMediaStream does not exist on the Swift side

[samgabriel]

@hthetiot this is continuation of #605 and the fixes from #592

[hthetiot]

@samgabriel let me know when ready for review.
Overall look ok, but I'm not sure that necessary to add the property but I will validate on final review.

[hthetiot]

@samgabriel can you handle this review from previous PR here #605 (comment)

trackId and rtcId aren't actually supplied, so this change didn't add any value.
