Allowing empty routes

[Bluenix2]

Summary

I have an API structured and use Mount('/resource/{resource_id'}) however this causes issues, because now it is impossible for me to define a route for /resource/{resource_id}. I am forced to use /resource/{resource_id}/.

Code examples

My code currently looks like this:

Mount('/resources/{resource_id:int}', routes=[
    Route('/', ConfigEndpoint),
])

...however I would like to be able to define a route with no path like this:

Mount('/resources/{resource_id:int}', routes=[
    Route('', ConfigEndpoint),
])

I've run into this as well! I'm trying to think what the cons would be to removing this check. I think we'd need to modify Mount in possibly backwards incompatible ways, but I'll have to check to make sure.
