[collaborations] Ignore OnTabGroupAdded if already opened locally

During shared tab group join flow, collaboration controller opens
the tab group locally in the tab model. However, there is a race
condition due to which sometimes the OnTabGroupAdded observer
event from TabGroupSyncService arrives later (probably due to
PostTask) which tries to create the group again in the tab model
which leads to an assert. This CL ensures that the later event is
ignored quietly instead of crashing.
