wallet2: key image import fixes

Browse source 
- return the right output data when offset is not zero
- do not consider import failed if result height is zero
  (it can be 0 if unknown)
- select the right tx pubkey when using subaddresses (it's faster,
  and we might select the wrong one if we got an output using one
  of the additional tx keys)
- account for skipped outputs for spent/unspent balance info

"spent" is arguably wrong, since it will count spent change
multiple times as it goes through receive/spend cycles.
