Jaya Allamsetty 40a485ec6c Thumbnail reordering and participant pane enhancements.
* fix(participant-pane) Use the sorted participant list from redux instead of sorting it on every render making it better performant. Match the participant order with that of the order in the filmstrip. Also move the participants with raised hand to the top of the list.

* ref(filmstrip) Move enableThumbnailReordering flag to testing section.

* fix(participants) Add new selectors for getting sorted participants.
