The mysterious blank item was just a mis-used layout

Was expecting the chips_waiting_for_directory_search layout
But was given the chips_recipient layout
Fixed this to use the correct layout
fixes b/6546713 Blank suggestion is sometimes shown even if nothing was typed
that's at least part of the problem
why it shows up "uninvited" is another question
