Fixed keyboard navigation for QTableView

Keyboard navigation didn't work in the following cases:
  - The last column was disabled and we pressed the tab key when at the 2nd
  last column. (See ref. task).
  - Spans with their anchor column or row hidden or disabled.
  - Navigation would not preserve the original row/column when traversing a
  span horizontally/vertically.

Auto-tests submitted with this commit.
