Invert precedence of content in ActionDispatch::Static

This commit inverts the precedence in ActionDispatch::Static so that
dynamic content will be served before static content. This is so that
precompiled assets do not inadvertently get included when running in
development mode - it should have no effect in production where static
files are usually handled by the web server.

Closes #6421
