Fix T80899: Crash on editing multiple UVs of multiple different objects at the same time

The issue was two fold.

First something sets the loop element tag and doesn't clear it before
the UV code in question tries to use the tags. Added a sanity clear to
make sure that it operates on a clean tag state.

The next one was that the UV maps in question had quite a few points
that had zero length UV loop edges. This would lead to division by
zero.
