Changed error messages for non-breaking user mistakes to console.logs

When scaffolding out a website, I sometimes create routes for which no templates yet exist, with the expectation that templates that do exist will still render properly. The current error-throwing behavior for non-existent templates, while very helpful in informing the developer of incomplete routes, also prevents working routes from rendering. A console.log might maximize helpfulness and usability in this case.
