Dustin Carlino dfbd9785f3 While merging adjacent perimeters for the LTN tool, don't proceed if
intermediate results can't be turned into a polygon. It'll break
something later. #841

There's a particular bug where a perimeter can be turned into a polygon,
but after collapsing internal dead-ends, it can't.

If we don't do this, the LTN select boundary UI crashes, and reasoning
about block -> neighborhood mappings gets very hairy. I'd like to
address all the root causes of failing to make a polygon, but until
then...

TRADE-OFF: it _really_ slows down the select boundary UI.
