Previously, when you attempted to bootstrap a component that had a
router-outlet using ngsummaries, it would complain that the component
was not provided by any module even if it was. This commit fixes a
mistake (AFAICT) which caused the lookup of the component in the AOT
summaries to fail.
I believe this change is safe. I've run the affected tests within Google
and there were no breakages caused by this change.
