Fix incorrect detection of filled zones changes in DRC check. 

Commit 6006703798 fixed a crash but broke the filled zones changes detection.
Filled zones were always seen as not up to date due to the fact the filled areas were cleared too early.

The up to date detection is also optimized: the old filled polygons are no longer stored.
Instead of, the MD5_HASH is calculated and stored before clearing the filled polygons.
