Summary: Segment's check image not removing sky clumps in

Details:
In the check image, each step is shown as a separate extension. Segment first
finds all the possible clumps in a large tile, but it doesn't use all of them:
many of the small ones are removed before going to the S/N phase. Therefore
there are two extensions: one for all the clumps, and another where only
clumps that are used for S/N calculations are shown.
I just noticed that when a tile has no usable clumps, none of its clumps get
removed in the check image. This is very confusing! I am working on the fix.
This bug has no effect on the final output of Segment, its only in the check
images.
