Catrope 79e4b139fb (bug 42212) Fix JS error when inserting after alien at the end
TransactionProcessor was using parentOuterRange without checking whether
it was present, so it was exploding for indexInNode results.

Now checking for parentOuterRange presence, and falling back to
nodeOuterRange when missing.

This fix causes inconsistencies with zero-length text nodes. We should
fix these eventually, but for now I've just made the unit tests
tolerant of zero-length-text-node deviations.
