Fixes crash in Assistant.

Root cause of the crash was committing a query without first having
pended a query.

This can occur in a notifications flow or a device actions flow in
which an interaction did not originate from the UI.

We rely on pending/committing the query in the interaction model to
clear the previous query from the UI. The fix, in this case, was just
to pend an empty query so that we have something to commit.
