Optimize Edb initialization for die designs (#966)

Several times die designs don't have any component defined. The changes
in code are made to reduce the Component initialization time in this
case which significantly reduces the Edb initialization time by ~50%
especially when there are >100k Groups in the layout.

(cherry picked from commit 40cc8f6)
