ui: use correct union field for key number

The code converting key numbers to QKeyCode in the 'input-send-event'
command mistakenly accessed the key->u.qcode union field instead of
the key->u.number field. This is harmless because the fields use the
same size datatype in both cases, but none the less it should be fixed
to avoid confusion.
