Redirect middleware not hitting single-entry endpoints

[CasperWA]

With the addition of the human-readable landing page, the redirect middleware was changed to avoid infinite loops on the base URLs.
This also means that single-entry endpoints are no longer redirected from /endpoint/id/ to /endpoint/id.

I don't think this is an issue (https://optimade.herokuapp.com/optimade/v0/structures/mpf_1/ redirects fine for me); the problem was that the slashed endpoints e.g. /structures/ had a defined response (i.e. query structure endpoint with a blank ID) but in this case the matching response is still just return the single entry endpoint.

Do you have a counterexample where it doesn't work?

[CasperWA]

It must be a thing of heroku then, starting the server locally and going to http://localhost:5000/optimade/v0/structures/mpf_1/ renders the implementation in a state where it tries to find id mpf_1/ (I believe) so it doesn't work - but maybe that is actually the desired result? Since / should be allowed in the id, right?

[CasperWA]

I think we should close this, since it is not desired to have the final / removed for single-entry endpoints as / is a valid character for ids.

Closing this, as per my last comment, it is not desired to have the final / (forward slash) removed for single-entry endpoints, as the slash may be part of the id.
