Title: Current code doesn't check for existance of env['action_dispatch.request.parameters']

issue_renderers/rails.rb doesn't check if env['action_dispatch.request.parameters'] is not nil. This can lead to an exception being raised. The change below fixes this.

I don't yet know how to test this edge case.
Any pointers and I'll gladly add a test case.
