Check for empty children after dropping overlapping ranges.

Before this changes, the logic checked for empty children before
DropRangesThatOverlapNonOwned in CoalesceOwnedMemory.

This could lead to a NULL added to the children vector, which will
later lead to a crash.  Instead check after drop ranges.
