core: don't send key_pressed signal again for the same key press

Browse Source 
If you press an incomplete key sequence, previously WeeChat would send
the key_pressed signal again for the same keys on the next key.

E.g. if you press escape and then 1, previously you would get the
key_pressed signal with signal_data `\x01[` when you pressed escape, and
then key_pressed with `\x01[` again when you pressed 1 (plus key_pressed
with `1` for the 1 key). So two signals for the escape key, even though
it was only pressed once.

With this patch, you only get one signal for each key press. So one with
`\x01[` when you press escape and then one with `1` when you press 1.
