UI: Fix Connect proxy tag (#6343)
This fixes a race condition in the pseudo-relationship between a
TaskState and a Task that was causing the Consul Connect proxy tag
to sometimes show on the wrong task. There’s no direct Ember Data-style
relationship between a TaskState and its Task; instead, it’s determined
by searching for a Task with the matching name. The related Task was
sometimes stored before everything was ready and not recalculated when
the name became known. This ensures the relationship is accurate if the
TaskState’s name property changes.
