Maintains flush semantics with Templatizer stamping (relevant to fastDomIf, which is a switch between Templatizer-based stamping and runtime _stampTemplate-based stamping). Works around an issue with noPatch where nested undistributed dom-if's won't stamp. The changes to the tests are to remove testing that the full host tree is correct since the host doing the runtime stamping will no longer be the DOM getRootNode().host at ready time (this is exactly the case with Templatizer, whose semantics we intend to match).
