Blocks with tile entities don't get removed when you clone / fill an airblock to their position.

When you clone an airblock to the location of a previously to that location cloned comparator, the comparator should be removed.

This doesn't happen, and instead the comparator stays and when you rigthclick on it, it disappears.

Steps to Reproduce:
1. Clone a comparator to a new location.
2. Remove the original comparator.
3. Run the same command.
4. The comparator is still there.
