[Bugfix beta] Route#render name vs viewName precedence fix

Fixes #4248: Passing an explicit name parameter to Route#render
should not have the associated view for that name be overriden
by Route#viewName.
This ensures that in the case of rendering to multiple outlets, and
later changing the viewName property, the only outlet to have its
view changed should be the main one.
