Normalize trailing slash for collection on self links

[vnen]

It's usual for collections to end the URL with a trailing slash. I know the server answers the same way to requests with and without a trailing slash (and that is good), but I would like to always show the trailing slash in the self link when referring to collections.

The spec doesn't touch this point, but I believe the self link should always be the same for the same resource. Right now it only reflects whatever the client has requested. So a request to /articles results in "self": "/articles" and a request to /articles/ results in "self": "/articles/". They have a different link but refers to the same collection.

This also complicates my integration tests, because I have to be consistent when making the requests to always use the trailing slash, otherwise I'll have a false alarm.

My proposal is to always use the trailing slash for collections (since they are akin to directories in a filesystem) and always show that in the self link, even if the server responds to both addresses. I'm okay with removing the trailing slash too, but at least be consistent.

I agree with being consistent, and I also prefer the trailing backslash as a best practice. We will get round to addressing this at some point, but if you're willing to submit a PR to fix it we'll be very happy to review and merge it.
