- This is to make difference comparisons easier
- The only nodes that didn't have a `loc` were fake nodes we made for testing
- So this commit also fixes the `osmIntersection` code and tests.
- actionRestrictTurn will no longer "infer" the turn type
- restrictionType *must* be passed in - this is ok because the only code
we use this action (restrictions.js) already has inferred the type
- this simplifies what the action actually does
- moved the tests from restrict_turn.js that were really just testing
the restriction type inferrence over to intersection.js
(and added a few more tests for iD.osmInferRestriction)
These should not be a thing, and if they are, I'm ok with them
being treated as 2 separate ways. We can add code back in later
if it turns out to be a widespread issue in OSM.
