fix(chord_composer): do not consume orphan key release events

The key combo Control+v may end with Release+v without Control modifier if Control key is released before v key.
chord_composer should only consume paired key press and key release events. Consuming orphan key release events
will cause the system to repeat unreleased keys indefinitely.
