Sending unpin after clicking local video and unpinning remote.

If we:
 - pin a remote and click it, unpin is signalled.
 - pin a remote and the click another remote, the new one is pinned and signalled.
 - pin a remote and then click local. UI pins local, but unpinning remote is not signaled, fix addressed with this commit.
 - pin/unpin local, nothing is signalled.
