Revert "Use the number of shown hotseat icons instead of database items to store into the DB"

- We rely on altering number of hotseat icons, which does
  not reflect with the now-reverted change correctly. This breaks
  index values in the db when reordering in transpose (landscape)
- Reverting this change and adapting to our changes fixes the issue

This reverts commit 2d023e26.
