Review Comment:
   Confirmed and fixed in 695e659c. The task the search was made for now 
travels with it, and an answer whose task is no longer the one on show is 
dropped: switchMap only drops a search the next search replaces, and a task 
change is not a search, so its answer could still arrive and refill the list 
the task change had just cleared. A test flushes a search after the task has 
moved on and asserts the shown list is untouched; deletion-checked.
