Undo: be smarter about dive computer shown after deletion

When deleting a dive computer, don't just show the first
dive computer, but the next one in the list (if it exists).

Moreover, on undo jump to the previously shown dive computer.

Do this by keeping track of the before and after dive computer
number in the undo command.
