Missing commit for Power Press b73b41dcacd794ca1d8fbfd84ae189ff6c82b533
 * Combi events did not work for double/triple events if the secondary key was pressed (tapcount increased both for primary/secondary)
Using the secondary key should be optional (to change this requires deeper changes), but secondary should be allowed.
The patch changes so secondary is just ignored.
Secondary before primary could give sequence error too, but then the default handling is difficult to define.

There is a similar handling for triple-click and double-click without triple events, the second occurrence is also ignored.
