[BUG] Answer m-lines should match offer m-lines even when answerer doesn't support media type

[hassanctech]

Describe the bug The master sample right now adds audio/video transceivers. If we modify it to only have video -- when replying to an offer which has recvonly audio, instead of sending an m-line it will send nothing.

Need to modify the logic that determines the response to match m-lines in offer even when local transceivers might not have matching media.

SDK version number eac3e1656aa01b3f3d730fb80272d062fd7cb538 (latest)

Open source building

To Reproduce Steps to reproduce the behavior:

1. Modify master sample to have video only
2. Run test page (https://awslabs.github.io/amazon-kinesis-video-streams-webrtc-sdk-js/examples/index.html) in Chrome and select audio and video
3. Start master, and then start viewer
4. See error about non-matching m-lines

Expected behavior The answer (from the master side) should contain an m-line for audio but the direction can indicate it's not actually supported
