Show path provenance in result comparison

[aschackmull]

Would it be possible to get the provenance information from flow paths shown in the compare view as well? Currently provenance shows up nicely in the paths in the alerts view, but when paths are shown in a comparison between two path-problem result sets, then there's no provenance shown.

Potential related issue, from @owenmc on Slack:

More feedback on the same feature (I'm comparing lots of results right now): sometimes it seems to think that two alerts are different when I think they're the same. Everything that is shown in the comparison is identical. I know that I've changed the model for the sink from one defined in ql to one defined in models-as-data. Is that what is causing them to be considered different? I would suggest that we should be robust to this.

While we're working on displaying the comparison results, we should also determine whether the provenance info was affecting the comparison even though it was not being displayed.
