Title: failing test case that shows how a route's `lastRenderedTemplate` can become polluted

using multiple unnamed outlets on different views in the ApplicationRoute can interfere with future transitions using the correct outlet

the root cause is that `lastRenderedTemplate` is incorrectly set when rendering into the modal view's outlet from the ApplicationRoute

This arose from real usage in https://github.com/yapplabs/glazier project.
