Don't create query menu until after initial prompt. (see #3877)

A resize in the prompt will trigger a redraw, but the data won't be
loaded yet, displaying a blank screen instead of the previous menu.
Once the query is done, the data is loaded, but the menu->redraw state
has been changed by the resize.

We could manually flag a redraw, but it makes more sense visually
logically to just create the menu after the query and results are
loaded.
