Pistons drop in creative

Put the summary of the bug you're having here

What I expected to happen was...:
When breaking any type of piston in creative should not turn into an entity when destroyed

What actually happened was...:
When a piston is powered and you break it from the extended piston head it drops the piston as an entity.

Steps to Reproduce:
1. Make sure your in creative
2. Place a piston down in any direction
3. Power the piston
4. Destroy the piston by punching it from the extended piston head and it should drop the piston entity.
