js: prefer some puzzle size even if loading isn't complete

The js_canvas_get_preferred_size() function was declining to suggest a
size for the puzzle if document.readyState wasn't "complete".  I think
my idea here was that if the document wasn't fully loaded then I
couldn't trust the size of the containing <div>.  While this was true,
declining to provide a size didn't help much since the puzzle still
needed a size, and the size of the containing <div> was the best guess
we had.

Now that function always returns the size of the containing <div> if
it exists.  This appears to mean that puzzles don't show a brief flash
of being the wrong size on KaiOS.  That was particularly visible with
Flood, where the wrong-size version had borders around the tiles that
the right-size version lacked.  The containing <div> isn't used on the
standard Web versions, so there's no change to behaviour there.
