I wonder if this is due to file-wide messages, or maybe there is another property to use?
Anywho, happy to see this more resilient

I think we need to figure out whether this is a legitimate scenario. I would rather we fail fast on unexpected/invalid input than hide potential problems. And of course, if it is a legitimate scenario, need to have tests for it.

FWIW line numbers are way off for most of my error messages (usually 0:0). The fixes in this branch only get things running.

turns out this is a legit scenario, because folks can cause parse errors, which occur on the whole file and don't have a line/column/etc

@NullVoxPopuli @gitKrystan we need to get master unblocked. Can one of you submit a PR to fix or disable this test? I can't accept the current PR as-is because it has untested changes in it. It may be best to fix the test on master first and then work on the bug fix afterward.

I'm not sure I have enough context to get this to a mergeable state, but I'd be happy to pair with someone on it.

One of these commits is causing the error: ember-cli/ember-template-imports@v3.1.1...v3.1.2
I'm about to put up a PR fixing the test

@bmish because this feature is new, I'd be fine with leaving the test commented out for now -- there are a couple things with the position mapping in general that might need more in-depth looking, I think

Skipping the test in a separate PR is fine as a temporary solution since it's blocking master.
