[iOS and Android] local video stream keeps streaming even the call.stopVideo(stream) give a callBack without error

[AmyL219]

Describe the bug
I close my local video stream immediately(before call state switches to connected) after the call has started successfully. I got a response that stopVideoStream successfully, but I can still see my local video stream from the remote participant's device.

To Reproduce
Steps to reproduce the behavior:

1. Join a group meeting with callAgent.join(with) videoOptions has localVideoStreams
2. After get the join call success callBack, immediately trigger call.stopVideo(stream) and could get the success callBack before the call state updates to connected
3. In the app, we would consider we has stop the local video stream successfully
4. However, in the other participant's app, they still can see the video stream from this users

Expected behavior
Other group call participant shouldn't see the video stream from the user who has stopped the local video stream
