SpaceCadet: corrected bogus row & column info for injected keypress

SpaceCadet was sending a keyswitch event with the row & column coordinates of the wrong
key. The coordinates were coming from the keypress, but the injected event was for a
previously-pressed (different) key that's still held. With the mutable
`live_composite_keymap_[]` change, this meant that pressing (and holding) `shift` then
another key would result in only a single character, rather than a repeating
character. Regardless of the minor bug, using the row & col for the event was still
logically incorrect here.
