Fix MC matching for time based mode

Up to now the input and event numbers where added to the match when the match
was created. In time based mode the digi and match objects are not necessarily
created at the same event to witch the MvdPoint belongs. This results in
wrongly matching the digis to the MvdPoints.
Add information about input and event number to the pixel charge to store the
the correct information about input and event numbers. Use this information
when creating the match object.
