Fix for #177

Sorry for digging this up, any reason to not merge these changes ? Have been coming across this issue a lot lately !

Please could we get this merged? I've also run into this issue, and the patch resovles it for me.

This is my use-case:

router = web.RouteTableDef()

@router.view('/my_endpoint')
class MyEndpoint(web.View, CorsViewMixin):

    async def post(self):
        print(self.request)
        raise web.HTTPOk()

When performing a GET against this, the client sees a 500, and the console sees the KeyError.

After applying the patch, the issue is resolved, and the client sees the correct 405.

Is there a plan to merge this?

This is completely breaking using views with the library...

Please, merge this PR. I think that a signing of Contributor License Agreement is not working.

Any chance for merging it?
