list: a named task list is not a grocery item (V-520)

"добавь в список" was a marker in two places: task_phrases.json for task
capture, and listCapturePrefixes for the grocery list. ListGrammars is wired
before TaskCaptureGrammar in buildRouter, so the list claimed every one of
them, and takeListTag does not know "дел" as a list name — "добавь в список
дел хлеб" filed a grocery item called "дел хлеб".

The bare marker stays a grocery item, because an unnamed list already defaults
to покупки and the task side always names its list. A named task list now
declines in ParseListCapture, ParseListQuery and ParseListRemove, so the turn
falls through to task capture. The bare forms are gone from task_phrases.json,
so the data says what the code does rather than being shadowed by grammar
order.

Reversible if he asks for the other default: move the two bare phrases back and
the list will need to decline them instead.
