Improved 'move' command.

- Removed (accidental) printing of the task (without leading ITEM#) when checking for existence of the task; using empty check of task text as done elsewhere.
- Simplified error handling and using die() for proper exit code.
- Aligned verbose move message with the verbose output of other commands.
