Rendering "~" caches

This is happening because 2.3 is a lot less strict at parsing template filenames while at the same time much more liberal at what it allows a template to claim that is should match to...

So what happens is that we have a test.html.erb~ template that has no rendering handler, but still claims to be renderable for test.html requests through its accessible_paths.

0001-Template-without-a-known-template-handler-should-onl.patch will only render templates without a known template handler only when an exact filename is passed i.e. abc/test.html.erb~ or abc/test.js.

I fully understand it, but I think that files ending with "~" should be ignored anyway, since it's always a cache.

I don't know what went wrong, but the the fixture templates with ~ weren't committed (even though they are in the patch). CI server is going to be pissed :).
