Fix issue with task view task listener being disassociated

- This is a regression from ag/33196865 for existing tasks, namely when
  we are relaunching an existing task, we don't go through
  ShellTaskOrganizer.onTaskAppeared(), and don't end up migrating the
  pending cookie listener to a taskId listener, and we subsequently
  don't bind the task to the TaskViewTaskController listener

  For new tasks, the migration will continue to happen in
  onTasksAppeared(), but for existing tasks, we can also attempt to
  migrate when resolving the new task listener when the info changes

Test: atest ShellTaskOrganizerTests
Test: Launch Settings into a bubble/fullscreen repeatedly
