fix(large-video): respect update in progress when queuing update (#4078)

When a fade in/out animation is in progress, another large
video update can be queued but can try to force itself onto
large video. For example a pin can be in progress and while
the fade in/out animation plays, local video can change its
video type during the animation and forcing an update of
large video. This results in local video getting forcible
updated onto large video while the pinned video is left on
small video only.

+            && this.newStreamData.id !== container.id) {
